Is it true??

[Anonymous]

i heard from somewhere that all LGB locomotivs can make it around a R1 or R2 curve

is that really true?

[vsmith]

Yes, although they dont look very pretty doing it.

ALl LGB locos from the 0-4-0 Stainz to the 2-82 Mikado can negotiate an R1 curve.

LGB calls it the R1 Rule and it applies to every product they make including the big streamline passenger cars. As i said though , they dont look very nice doing it. The Mike has an articulated chassis and driverod linkages that will actually bend to allow for the tight radius. The GG1 will overhang the corners a good 5 inches front and rear while transversing an R1. This is Typical LGB.

Now, just because you can run a Mike thru an R1 doesnt mean you should plan your layout for it. Its still beter to build with the widest possible radius curves that work in the given layout area.

Enjoy!

Yes it's true.

now how they look going around that curve is all in the eye of the beholder.

i thought the mike would have that because on my dads marklin layout he has a BR 50 which is a 2-10-0 and it articulates around wheel number 3 and the drive rod thing to

but what about aristos mike??

[kstrong]

Not so with any other manufacturer. LGB is the only one which "requires" all its models to fit around its tightest curves. All others state minimum radius requirements--some more prominently than others. The Aristo mikado, if I recall, will run around a 4' radius.

4 feet i got one 5 foot! and and ive always loved the mikado! o boy hehe [:D]

[piercedan]

All LGB products will go through the R1 4 foot diameter curve.

Aristo and USA are making products which require 8 foot diameter and larger.

[Anonymous]

kstrong can u provide me a link with info on that statment about the 4 foot radius and the mikado.

[Anonymous]

All LGB stuff will go around a 1.1 M curve some will do it in half that.

The secret is in the bogies and untill i see one that is as good, you will never sell me anything else!

I do use some other brands for my exploding cars, gee you set one off in a tunnel and wow the noise is terrific.

I've seen 6 year olds act better than that, Ian.

Some folks aren't interested in foreshortened engines and 5" overhangs.

I've parked most of my LGB locos for those reasons, plus a lack of fidelity to scale.

"Suitable for Large Scale" doesn't cut it.
And, when engines are three different scales depending on where you measure them...

They run good, will just about follow an old Lionel 027 around, but ain't interested.

I thought there was a new 2-10-2 steam loco that will not go around r1 curves. Anyone know? Looks like an excellent start for a 2-10-10-2 Santa Fe, except oh the cost!

Regards, Greg

[vsmith]

Greg the new 2-10-2 WILL do R1's, I know cause I've seen it and the 5 inches of overhang at the rear. Nice engine though...

As for Aristo, both the Mike and the Pacific req 8 foot DIAMETER curves, thats 4 foot RADIUS, where all of LGB's stuff will negotiate a 4 foot DIAMETER curve or 2 foot RADIUS, just to clarify.

o dang i had some hope there [B)]

Hi Greg,

If you are refering to the 99 7222-5 it will go around a R1 radius, but even Mr. Schiffermüller - the designer of the engine - recommends at the very least R2 or as he would prefer R3. The engine has been run on R1 at several shows and various people have reported that the brass shavings from the track are quite noticeable in the tight curves. Perhaps LGB should get one of the vacuum cleaner cars to run 2 cars behind the engine. [;)][:)][}:)][;)]

A translation of the review in the GARTENBAHNprofi can be dowloaded from http://www.easternmountainmodels.com/pdf/1_05Pre.pdf

In the same preview issue you'll find a very good article on the prototype and the "How we designed it" article on the LGB engine.

Happy reading!

Wellllllllll .........have you seen the video of the considerably shortened LGB/Aster GG1 going through a R1 curve?

Rumour has it that some people have aquired special glasses which, with very selective correction - don't even ask how they grind the lenses[:o)][}:)][:o)] - will make LGB engines appear to be to scale , the overhang on R1negligibile and most everything about them quite close to prototype.

If I remember correctly TOC wears glasses, as do I, but neither of us has the particular type required to see things quite that way.[}:)][}:)][:D][:D][:D]

wait so if the 99 7222-5 will make it in a R1 curve...y cant the aristo mikado do it??
or did i miss something imporant on the articulated driverods on the 99 7222-5?

Very simple: The Aristo Mikado has a fixed driver wheelbase. Which means the drivers sit in a frame that is designed like the prototype's, no articulation!

The large Harz engine has an articulated driver wheelbase, as does the LGB Mikado. While that permits getting around R1, with the previously mentioned results, it also has the tendency of not straightening out after curves. The front section of the drive train will either point slightly to the left or right (depending on the direction of the previous curve) and the rear section will point the opposite way.

PS when in doubt: go fishing!

I have one of the LGB Mikados. While it will stay on the track through an R! curve, it creaks and groans a bunch and will derail at the slightest track defect. R1 switches are a different story. My Mike derails almost every time when trying to go through a R1 switch. It takes at least an R3 switch for it not to derail. Even then, it's got to be slow through the switch.

[Anonymous]

No. They claim it is, but with some locos it's definitely not recommended. I have one of their U Class 0-6-2s which managed to get its gearing out of mesh while following their claim (requiring the loco to be dismantled, adjusted, and reassembled - luckily no damage had occurred). I'm aware that it's a long 6-coupled wheelbase but I'd read the claim about R1 and believed it - when I get around to a fixed layout it will use much larger curves. Personally I wouldn't run anything larger than a Stainz or similar short 4-wheel loco on R1 curves for fear of damaging it. There's also one new model that might well hit their claim somewhat - the RhB 4-wheel baggage van. In stock form this gets jammed on R1 curves and leaves the loco with all wheels spinning (mine now has ball-bearing wheelsets and can handle R1 - did this as I wanted to add metal wheels and all I currently have is an R1 test circuit).

Do those LGB Mikados have blind drivers?

(*Disambiguation note: "blind drivers" refers to the tallest wheels on a locomotive not having wheel flanges. The leading and trailing wheels keep the locomotive on the rails.)

[Curmudgeon]

No.
They aren't even Mikados.
They are 2-4-4-2's.
The engine assembly is pivoted in the center, with slip-rods to allow comression and expansion.
It does a good job, but a 2-8-2 it isn't.

really? oooooo[:p]

The Mike does not have blind drivers. The only blind driver on the layout is the one with the throttle in his hand[:o)][(-D]

Is this the rail shaver you guys were talking about? I didn't bother to reread the thread before posting... I had a feeling Mikado wasn't right...

[Bucksco]

Say what you will about LGB but the 99 is one beautiful lok. I've handled it many ,many, times and never once have I broken off a detail part! Runs like a Swiss watch.

That's the one! BTW it is a very nice engine and people with large enough radii on their layouts have fixed the wheel base to make it behave like a "normal" engine.

But the Mikado discussion was about a different engine.
Anyone who would like to read the translation of the GARTENBAHNprofi review/comparison of the Aristo Mikado and the LGB Mikado can downlaod the PDF from here http://www.easternmountainmodels.com/pdf/4_03.pdf
