Right now I'll just start converting the cars I have, I'll add to them as I go, according to MR the T1 can haul 24 cars on straight and level track, and the E8 AB set can handle another 24, so the B can handle 12, so T1 and E8b can haul 36 passenger cars, now on 32-34" radius and a 3% grade (I don't know if that's actual or compensated) causes that figure to jump by that much.

.

SteveO can correct me on this if I get it wrong.

.

I believe when Model Railroader reviews a locomotive they actually measure drawbar pull. Then there is a straight line graph that equates to the number of "cars" that amount of pull theoretically equates to.

.

These are imaginary cars on straight and level track.

.

Expecting that number to be anywhere near how many passenger cars can be pulled up a 30" helix on a 3% grade is not realistic.

.

For example, one of my Stewart/Kato F3s can pull about 50 freight cars on straight level track. They can pull 6 cars up a 5% grade and 24" radius curve. I know this through real world tests and experiments.

I know that BLIs RSD 15 can only pull about 10 cars up the helix compared to the 50 of the review, to increase traction I could always add bullfrog snot.

OK, left the club, Casey El Presidente says another member has run 30 car Ethanol trains, if I wanted and had motive power up to the task I could run the long passenger trains, as long as the equipment is in good running order.

To increase the T1s already great pulling power I could see if I could get from BLI another of the traction tire equipped driver sets, swap out the leading driver set with that so it'll have two sets of traction tires, all the power pickup is in the tender anyway, right now it's:

Leading truck two axles, first "engine" a flanged driver set, and a blind set, second "engine" blind set, flanged traction tire equipped set, trailing two axle truck.

That first set of flanged drivers would get a traction tire.

Hmm I'd suggest you think about the possible consequences to the locomotives drive train. The gears may not be able to cope with the extra traction.

I am confused as to this desire to run this massive passenger train. It is almost appearing to be some sort of contest at thr\e club as to who can have the longest train. I would concentrate more on running a prototypical train that is trouble free and will run flawlessly around the layout, running grades and the helix. you may even refine the coaches to back through series of turnouts in the yard. To me that is more of an accomplishment than playing "king of the hill" most number of cars that pulled the 3% grade.

I have a small collection of IHC passenger cars, among the upgrades I wish to give them are, body mounted Kadee couplers, metal wheels, proper weighting, and I was considering swapping them from 2 axle trucks to 3 axle trucks. The cars have offset bolsters that I'll have to either find trucks that match or correct the position.

The kit I plan to use for the couplers is Kadees #451 "extended swing" gear boxes.

 

How small is small? 4 or 5 cars?  What you describe is easily doable.  24 cars, it's starting to beome a production...

I do not have IHC cars, but I have decent number of Rivarossi and Con-Cor passenger cars.  I installed 36" metal wheels in mine, which meant I had to shave down the brake shoes a slight amount with an Xacto knife. The cars are also seriously underweight, so I have been adding weight using old tire balancing lead weights.  They seem to track better when they are closer to NMRA RP.

The biggest issue I had was how "floppy" some of the trucks are with just a plastic pin to hold them.  I tried a 6-32 tap in the bolster and a screw, but it has not been completely succesful.

I thought about body mounting the couplers, but I ended up using the McHenry couplers as a snap-in replacement.  The Kadee #451 you mention looks like a good approach to body mounting.  I suggest you try it on a couple of cars and see how they work, and report back.

I was wrong about the grade, it's 30" radius and a 2.33% grade.

I'm going to work on the dozen I have an go from there.
