PCM announces a near HO BIG BOY, with and w/o “after cooler”. Does anybody know what is this? Thanks.-
The after cooler is just a detail part. Some Big Boys had it, some didn’t.
Thanks, Hoople, but what or where is it?
Total guess here but I believe it is the pipe loops on the front deck.

Follow the link, all you need to know I believe!
I you look at PCM Big Boy web photo, there it is such as an humongous device ahead the stack…should it be?
