@CAPPilot posted:Except for the last few built in 1946, the production engines had the port hole pilot. Here again the streamlining effort interfered with efficient maintenance of the engine, so all earlier T1s had the port holes removed by 1948. Here is my Lionel scale T1 in the T1's final configuration.
Since only the non-port hole engines were around between 1948 and 1952 (when they were retired), this T1 configuration fits right into my layout's era. It is one of my favorite engines and it is run a lot.

Thanks for the history. While I am nowhere as road or era specific as you are, knowing some of the history behind these engines is great. Is your Lionel version one of the TMCC engines from around 2000??? I have one packed away in the basement - it is a beautiful engine... I may just have to pull it out and give it a spin!!!
