An HO model of it has been constructed. Was a rather intensive process if I remember correctly as almost all the pointwork had to be constructed in one or two pieces. It mustve been the smallest prototypical continuous run track work in the world.

I dont have any ideas for this, but most coaches dont have doors in the middle. Especially not the Super Chief. What kind of coaches are you trying to build?

Honestly, for the Jupiter, you need to use the XL drivers. The L drivers are too small for the early American types. And there are plenty of photos online of the Jupiter. Theres even a film on youtube about the restoration of the locomotive. The way you say "what the loco was based on" doesnt really help. Many early American types were varied in design, so for the Jupiter, you need to look at the Jupiter alone. It will not be hard to find say the wheelbase, the length, the height, and all that, and from there and good photos, you should be able to build an accurate model.

You have the carrying wheels wrong. Its a 4-6-2 not a 2-6-4.

These are very nice. Would look good in the LIRR lettering, though that may be a little influenced by where I live...

Youll have issues with the wheels. Since theres no axle, theres no quartering. Id take out the inside valve gear to keep proper quartering. You wont see it anyway.

I can tell you with the double crossover you will not be able to run two trains at once.

If you could gear it to the drivers and somehow hide it in the boiler, it might make for a fast loco. Though how youd fit it I dont know.

Nope. None. Even before America adopted the knuckle coupler, all the inter car forces were through the drawbar.

All that bothers me is that it has buffers. Though it is nice, and with the pf motor, it will be fast. My General had it and it was fast and hard to control.

One of my favorite Lionel animated cars is the Shooting Sheriff car. I always wanted to make one in Lego but I cant work out the mechanism in Lego. Your car looks great. If only the moving bits could be done.

You just keep making awesome things.

If you really want to be ambitious (and want to murder your wallet), you could do 8 motors, 2 in each unit. Would be interesting, and you would get lots of power.

First, the name of those rods is coal rails. Second, its hard to implement the lego motor without altering the length. If you want accuracy, then the motor would either go in the loco, or a trailing wagon to push the whole thing. The wheelbase seems about right, but I think the wheels are undersized. I believe BBB's smallest drive wheels make good tender wheels. Lengthening the body of the tender may help get rid of the front footplate which isnt really there. In final, the rear shouldnt push out that much. Looks odd in Lego.

You will need one more string for the bucket tilting. You should build a simple stand to keep it stationary while you test string motions. Your video shows the difficulty with doing this if you dont have a steady base. Hard to see whats in tension or not.
