Quick question about #4 TO and larger engines.

I didn't think so.I was thinking of E-baying the T55 and getting a couple BLI SD40-2's instead anyways so now I have an excuse to do it.I'll see what happens,thanks for the input.
 
I have atlas snap-switches, so I am not sure about #4's, but I have an Athearn AC4400 and I can do those switches, but I had to add Kadee long shanks to both the engine and car behind it, so I'm sure most people wouldn't think that is acceptable.
