Get a bigger computer.
I have the track plans for the New Haven Railroad's main classification yard that was located in New Haven, CT. Do not bother to google earth this, I've been made to understand that there is absolutely nothing left of it.
The name of the yard was Cedar Hill and it had two humps one on each end. If interested in these track plans private message me and give me an e-mail for forwarding. This was a massive yard it could have been even bigger than Rice Yard in Waycross is now.
