Since P5s were mentioned some of those as well.
A Sunset on my 2nd O gauge layout circa 2007.
An MTH modified from a TCA public event in Mesa, Arizona in 2003. I have since sold this locomotive as the details were too pronounced for my liking.
I replaced the MTH model with this Overland one. Is it a better model? It depends on your definition, but it more closely suits my interests and I prefer the more subtle detailing.
