I have the K-Line scale Hudson with MTH's PS2 and smoke. It's a really nicely detailed locomotive and performs great. Also the NH Ep5 pictured above. Their F3's/F7s are very nice scale models with great detail as pictured here in the PRR. It is an ABBA. Have the Northern Pacific ABA too with 21" Weaver Aluminum cars. Recently I've acquired several of the 18" & 21" K-Line aluminum passenger sets that are terrific even after all these years as well as misc freight cars- especially die cast hoppers.
