There comes a time in every project when you realize something is wrong. This time, it's really wrong. Catastrophically wrong, one might say. The turn radius on the layout are too tight for the modern passenger coaches. The Amtrak coaches made it through fairly well, but the new NJ Transit double-deckers simply cannot make the turns. This has forced a major shift in the track plan, which I'll explain below.
As for the title of this post, yes, it should be sung to the tune of "Tramp! Tramp! Tramp!"

| The Eastern Curve that's too tight. The NJ Transit coaches derailed constantly. |
These curved track sections are the tightest radius Kato offers that are meant for standard trains. The problem seems to have been that I originally built this benchwork thinking the biggest rail cars would be the 47-foot Civil War era coaches. Then once I switched to a modern era layout, I forgot the turn radius would be too tight for the much longer modern coaches.
You can see how much wider the curve radius will have to be to comfortably accomodate the modern era coaches. There's not much choice here but to add on "wings" of some kind to widen the surface area on which to build this new track plan. I'll also have to purchase additional track, as I only have the wider turns from the original M2 Kato set, which we want to save separately.

| The Middle Inside Curve, also too tight for the NJ Transit coaches. I'll have to rip up much of this. |
The middle inside curve area just down the line from the trailer yard was also too tight for the modern coaches. This will have to be ripped up and realigned with a wider radius curve. I'm really upset about this part, due to all the ballast I set down for the yard area. That's going to be a real pain to remove. My estimate is that the new track will have to shift right down the middle of these two current tracks. But I'm not sure yet.
Somehow, the outside/farside curve is not having any derailment issues with the new coaches, despite being the same radius. My conclusion with all this is that the turn radius would have been tolerable is laid down exactly perfect, but they must have been just a degree or two too tight. The tunnel is a similar situation, where I could "untighten" the curve inside the tunnel and the coaches seem to do alright.
This is so frustrating. But as I've said continuously through this process, I'm learning so many hard lessons that I really don't want to have to learn during the Civil War era layout down the road. That layout will have to be near perfect and I can't afford any screw ups like this.

I do work on some small side projects from time to time. This one is a new wood load for the DC Atlas 4-4-0's. It looks much cleaner than the previous wood load, and hides the tungsten putty very well.
