MTH DCS vs. Lionel TrainMaster DCC
Posted by barclaysierra on Tuesday, December 7, 2004 4:22 PM
I'm in the same mess I was when buying a digital camera. Couldn't find anyone selling them who could explain and demo satisfactorily. Short version, I'm looking at DCC systems for my MTH system (now a Christmas train on the floor for grandkids, but soon to be a perm layout in garage for both of us).

Looks like MTH's product is better, does more and can run both MTH and Lionel. However, I've seen at least one web article that indicated some reliability problems, and the hobby shop that has them says they have had problems, won't even demo...want to push Lionel. I think I only need the remote controller and track interface unit, as my transformer that came with original set is 100 watts and I only want to run 2-3 trains max.

Lionel product looks like it can run MTH, but maybe not all functions, like scripted dialogues, voice recording, etc. However, I only have that on 2nd hand account from a guy I met in the hobby shop, who claimed he was doing it. Again, looks like I only need the basic unit and remote...maybe a Lionel transformer too?

Hobby shops have been little help, the "DCC Expert" only works a few days a week and hasn't shown up for work since I started asking. The rest of the crew seem only interested in selling the Lionel version.

I have a DCC ready MTH loco with Proto 2.0 sound. Great little engine with incredible sound. Looking for another.

I would be grateful to hear any experience or recommendations from anyone who has worked with both systems.

HI JB and Welcome to the CTT forum


I believe we can help you. By any chance do you live in the southern part of the state [?]

OK lets start off with a little of confusion. All these letter are so darn confusing.

DCC is a DC command system for most commonly used in HO trains.

DCS is MTH command system for AC O gauge. They also have one for DC in Gauge One and also HO, but lets not go there for now. I believe you want DCS for O gauge.

I have been running DCS for 2 years without any problems. It consist of:

1. a TIU = track interface unit and
2. a remote control

That’s it. If you wish in the future to want to run TMCC (Lionel) then you will have to add the Lionel Command Base to the TIU.

Here is a link that can answer some of your questions

If you need more help, just ask

Tom summed it up nicely.

Both systems are extremely reliable. Of the two, DCS (MTH) is more advanced and, if you have a Lionel TMCC Command Base and the special MTH cable to connect it to the TIU, it can run TMCC locomtives in command mode (in addition to MTH PS-2's). You can also run conventional locomotives from the DCS handheld.

Like Tom, I have been running DCS for two years (have been doing demos for MTH for a year and a half) and find the system to be very robust and easy to operate.

If you have or plan to purchase primarily MTH Protosounds 2 locos, you'll want to get DCS instead of TMCC, for reasons of ease of operability, access to all PS2 functions and overall compatibility. As with all such equipment, you are better off having a knowledgeable local store or expert hobbiest in case you run into glitches. If you don't, I suggest you make sure you purchase your equipment from a mail order operation that is willing to provide advice and support by telephone or email (some good ones are Nassau Hobbies, Ready to Roll, Island Trains, etc.).

As pointed out, you can always later add a TMCC command base and a TMCC cab-1 (about $90-110 for the package at most discount hobby shops).

I'll see your four and raise you four more Buckeye. My TMCC (minus one burned out early Powermaster) has been extremely reliable and simple for eight years[:)]. Just make sure you have an up to code, grounded outlet to plug the command base power supply into. That accounts for about 95% of the problems folks report with TMCC.

For someone new to command I would recommend Lionel's TMCC because it is much easier to use and simpler than MTH's command system. MTH's system may or may not require special care in wiring the track whereas TMCC will not have such limitations.

Saying that; if you already have an MTH Proto-2 engine; I would get MTH's DCS, only because you want to take advantage of the features in the engine you have;

As has been said, you can always buy a TMCC unit and connect it to MTH's TIU box if and when you purchase a Lionel engine with Command Control.

I have been using tmcc&dcs so far tmcc is easier to use have had trouble with dcs not reading signals sent . I seem to be getting interference from something but what i haven't a clue? you can use tmcc to control ps-2 locos in conventinal mode you just can't acess the diff programs. you may want to hold off on these systems as train a studios is going to release a computer setup which will make hand held obsolete!!

Stpaul – I would first check and see what your track single strength is. If you are above a 7 you should be ok. Do you have a cordless phone that operates in the 900Mhz range [?] or do you use a cell phone when you are having troubles with your DCS [?]

IMO DCS is very simple to install and operate. Two wires from the transformer to the TUI and then two wires from the TUI to the track.

OGR makes a great video on both and here are the links
http://www.ogaugerr.com/cgi-bin/shopper.cgi?preadd=action&key=V-DCS-01

http://www.ogaugerr.com/cgi-bin/shopper.cgi?search=action&keywords=Trainmaster

It not a bad investment and training video.

Thank you all for your input and advice. Since I'm sticking with MTH Proto Sound 2.0 for the moment, I'll try the DCS. Sounds like most of you have had a positive experience with it.

And to whomever asked, Folsom CA is in the northern part of the state next to Sacramento.

dcs system is the better system between the two systems-more options and display screen to inform the user of the different options and processes-i run 4 loops with 3 on the dcs system and one on only tmcc system-harder system to learn at first, but after mastering the system, far superior to the tmcc system-only use the tmcc system because i have the system and do not want to use the conventional way of controlling the one loop with the transformer handle

Go with the DCS. Complicated to operate is BULL S. Mine is running on a temp floor layout with old Lionel track and temp wiring. NO PROBLEMS. I went with DCS because I can add the TMCC module and run both. Why buy two complete systems? Now you can run all command trains [no matter what brand] at less cost and equipment.

Tom Taras,

I agree with you about the display. It is a huge improvement over the little plastic templates that fit over the keypad on the TMCC Cab-1. I don't like having to stare at the Cab-1 to try to figure out which button to push and I keep loosing the templates (I greatly appreciate Lionel including a new one with each locomotive).

It is also a lot simpler to press a button permanently labeled "Smoke" to turn the smoke on or off and a button permanently labled "Headlight" to turn the headlight on and off as opposed to having to remember a code.

Just out of curiosity, why do you have the TMCC on one loop and DCS on the other, as opposed to both the DCS and TMCC signals on all loops, all the time?

The one part I really like is when I change engines on the layout, you just have to press the ‘READ’ button and DCS finds your active engines. Start them up and run.

I have a cordless phone 2.9 This none read problem on remote screen is very speradic& even will do things with out be asked. mth knows me well at tech site I sometimes even have a problem getting tiu to accept the fact that it is avalid id#. sometimes if I shut it down and wait till next day then it works fine go figure !! this is also 2nd tiu only 1-month old no better than first one. I also cannot get mth system to run a tmcc engine! I do all the programing according to instructions but no response- take cab-1 & type in same id# and its up & runnin. I am not Impressed with DCS so far am concidering goin back to toggle switches & enjoying myself instead of being frustated.

Stpaul,

If anything, DCS response should be more solid than TMCC.

Which cable are you running from TIU to Command Base? Is there a black box in cable?

Which software load are you on?

Which TIU do you have (Rev I, Rev. H1, or Rev. G)?

Does software in Handheld match software in TIU?

What type of wiring do you have to the track (buss, star, wire type and gauge).

What transformer are you using?

Sorry for all the questions, but I would like to assist, if possible. I am sure that Tom would also.

In answer to your questions. 1. yes cable has black box. 2.I had local hobby tech download3.0 on old tiu. 4. I bought a new tiu 2- weeks ago no indication of rev date etc shown on box. but both tiu&handheld workedfine until last 2 days.5. I bought ogr's 14 gauge wire that is dcs compatible.6. transformer is z-4000. news flash yesturday had 3- mth ps-2's going 2 on same track tryed to slow rear train down& no response tried other 2 no response 2 trains on colision course in desperation hit e-stop on handheld no response shut trans off since then I get tiu error or no active dcs on track . handheld shows all 3 locos as inactive cannot get tiu or h held to read trains on track. is signal better -dcs-tmcc not so far& yes all 3 loco's respond to tmcc no wire change just fire up tmcc& poof it all works !!! ready to throw system in trash where it belongs.

Stpaul,

I will be happy to assist if you want. Properly set up, DCS will be more solid than TMCC (which is really solid). We just fire the layout up and DCS works with no problem. Not trying to be argumentative, that is just the way it works. We have run up to 10 trains at once through one TIU on four tracks (combination of PS-2, TMCC, and conventional.

Just out of curiosity, where is the TIU mounted. I keep seeing people mounting them flat on their back under the layout and that is not usually conducive to the system working correctly. It is definitly "line of site".

If you do a track signal test, what is the result?

Are you actually located in ST Paul? If you are in California, you can come and run with us sometime to see how it is supposed to work.

Anyway, the offer to assist is there if you would like it.

Not sure of tiu on its back. yes it sits on its 4-pads on a wood table under layout but is on 4 metal casters so all electronics are not more than 1-foot under table als has 1 1/2 feet of open air space all around it . now my question is how can it work for hours just fine & then decide not to . If signal was issue would't it show up most if not all the time??

St Paul,

The first thing you might try, is tethering the Handheld to the TIU with a four wire telephone handset wire. If that cures it, it is definitely an RF problem.

If the tethering cures things, first make sure that the RF boards in both the TIU and Handheld are both seated firmly. Occasionally one will come loose and that will make things rather interesting.

If both boards are seated correctly and the problem persists, try getting the TIU out in the open, and mount it vertically. An air gap ( as you described) is not a substitute for "line of site" from an RF standpoint for our purposes. I had the TIU under my Super O layout and found that, depending on what was in between the remote and the layout, I could get the signal blocked, causing a temporary loss of control. There is one layout that I visit that has all the TIU's mounted under the table. Depending on where I am standing, if I hold the Handheld above the surface of the layout, I may experience a temporary loss of control. If I move the Handheld under the table, control is instantly restored. When the Super O layout is taken out of storage, the TIU will be mounted on the wall (next to the Command Base) well above the surface of the layout. The object is to be able to control things properly no matter where the Handheld is relative to the layout.

Both of my temporary control setups have the TIU mounted vertically and out in the open. Both have excellent range and do not experiece the issue you described.

With regard to the TIU being on its back: There is a small wire antenna inside which is about two or three inches long mounted to the RF board. It runs parallel to the long side of the TIU. If you stand the TIU up, no matter where you are in the room, the same amount of antenna area will be presented to the remote. If you lay it on its back, if you are to the side of the TIU, you will have the maximum antenna area presented to the Handheld. If you are off the end of the TIU, you will have essentially no antenna presented to the handheld . The difference between "I" and "." in terms of antenna area. I learned about this from flying R/C Helicopters and airplanes. Pointing the antenna directly at the airplane when it was close to the ground (especially with the early radios) could be a sporting proposition (loss of control there was usually somewhat expensive).

In terms of working for x number of hours then stopping, we sometimes have things running all day at demos without shutting down and have no problem (sometimes we all shut down to eat). I am suspicious that you may be standing in a different place, relative to the TIU when you experience the problem, or there is a wiring problem on the layout which is causing temporary loss of signal (reflection or out of phase condition) so the problem occurs when the trains are in a certain geographic area of the layout.

One other area where I have experienced a loss of control (on one of my own layouts and on one that I was troubleshooting for someone else) was a slightly loose connection where the track wire connected to the TIU or the MTH Power distribution panel. It took a while to find it in both cases-in both cases the connection was sufficiently strong for the voltage to pass through to the track, but not the DCS signal. In both cases, cleaning an tightening the connection cured it instantly (took longer to find than to fix).

Let me know if any of the above is useful to you.

As far as wiring is concerned, are you familiar with Barry Broskowitz of the OGR forum? He developed guidelines for wiring DCS layouts that have become known as "Barry's Commandments" (he does not care for the term). At any rate, these guidelines have helped a great many people have a very successful experience with DCS. I use a modified version of this. If you want I can post the link to it.

Anyway, the number 1 issue is to eliminate RF problems between the TIU and the Handheld as a possible cause of the problem, then look into the wiring.

I am leaning more toward the RF issue at this point, as opposed to a wiring issue as you mentioned that you sometimes cannot find the TIU with the remote and also that the "E-Stop" feature failed. Neither of these failures should be the result of a wiring issue and are probably genuine RF issues.


Sorry to go on so long. Please let me know if any of this helps.

Thank you.

Do both remote and TIU have same software load? When 3.0 came out, it did a number of things including re-structuring the memory allocation between the Handheld and the TIU. If one of the components has 3.0 and the other an earlier software load, then you will have difficulty. If both components were upgraded to 3.0 but both were not re-set afterwards you will likewise have problems.

Please let me know.

What area of the country are you located in?

have you checked the batteries in the handheld.

make sure that they are fresh and making a good connection. I stuffed a piece of foam popcorn under the battery cover to help press the batteries into the handheld.

[:D] to all who helped!!!!!!!!!! I checked all boards tiu- remote they were alittle loose. batts good in remote. got original 2 3.0 setups back together used a temp track to get things goin again took 2-hrs but so far test track is working. I have discovered thou you can't have any metal - screws locos anywhere close to antenna area as it will show as rf error go figure. how can I mount TIU to table in vertical pos so it can't fall off??? if I use screws will they need electric tape or ? to keep electronicsfrom getting fried??? now comes the real test will all this work on the layout . I certainaly hope so. will let you know results latter. THANKS TO ALL FOR THE HELP!!!!!

Stpaul,

The best way to mount a TIU that I have found, is velcro. I actually learned this from a friend who runs an "all Lionel" shop in Anaheim (the Toy Train Shop). A couple of years ago, when I was trying to figure out how to mount my components, he showed me how he did it. He had a vertically mounted sheet of plywood with his Command Base, SC-2's etc. mounted with velcro.

The industrial strenght velcro from Home Depot works really well. It is about two inches wide. Two strips of it will hold the TIU very well.

It will stick great to the back of the TIU. but if you are mounting to plywood (as I did), staple the other side of the velcro to the plywood, as the sticky part of the velcro does not hold well over time.

In all honest, I do not remember what the "T" is for but I will research it.

[:D][:D] I wired up the main lines from new tiu spot works fine will try velcro idea thx. I'm only getting 4-5 read on track signal on inner loop. outer loop is mostly check track only 1 section reads as #1 back to wiring may have to isolate tmcc from dcs& IC controls- block power etc.

Your single strength are pretty low. You may want to consider cleaning your track also. Are you using track with a blacken center rail [?] If so, you may want to remove the black from the top of the rail.

Stpaul,

Glad it is getting better. Now for wiring:

Please do not separate your TMCC and DCS wiring, they will work fine together. Can you describe your inner loop (i.e. length of the loop, type and gauge of wire, number of connections, number of sidings, etc.)?. You mentioned block control-the method that you use to turn blocks off and on may severly impact DCS signal. Can you describe how you are accomplishing this.

Thank you.

FYI:

I am running 14 gauge paired speaker wire. Largest loop is approximately 90 feet in length-broken into four blocks. Blocks are created by insulating center rail only with plastic pin. One lighted connection at each end of each block. All connections radiated out from center of layout. One TIU channel supports one loop of track (all four blocks). Solid 10's all around. Each siding ends in lighted MTH or Lionel bumper. Block control is for sidings only-blocks are turned on and off by knife switches on 437 Switch Tower.

Photos of demo layout from last November-MTH PS-2 and Lionel TMCC both operated very well on the same track at the same time!:





You can see paired lock-ons on tracks in foreground. There is an insulated pin between each pair of lock-ons. This kind of wiring is overkill but works very consistantly on a large layout which is put together and taken apart constantly.

Please note Lionel Command Base between TIU and AIU in control box in center of layout. Both DCS and TMCC signal are broadcast from all four TIU channels to all tracks, all the time.

Also please note original Lionel post-war accessories-all operated through DCS with AIU.


Thank you.

I have aprox 25 foot long oval x 9.5 feet wide inside outer slightly larger. I'm using Block power boxes from I.C. Controls to a terminal strip from there goes out to 4 isolated blocks per loop of track. For DCS I by passed block power controlers & went directly to terminal strip & hooked fixed outputs from 1&2 to each oval of track. I'm not runin power thru TIU just sending DCS signal to track.I'm using a mix of gargraves& ross track withBlk'nd center rail I used scotch brite pad on offending areas but no better than before removal of blk'nd rail. outside oval I need to go thru each connection& verify good& tite. also I tried Soldering powere feeders to rails cuold this be aproblem? I used spade connectors on previous layoutsforced into track from underside of track opening I wonder if I should try that on 1 section of isolated track& see if signal gets better? what do you folks think??
