This past weekend, I was running my Lionel Lehigh Valley northeastern caboose at at train show. After a while, I started smelling a funny aroma comming from the layout. I quickly realized the heat from the smoke unit was slowly melting several of the plastic window inserts. I was kinda surprised by this. I can only guess these smoke elements are not designed to operate on the higher voltage required on TMCC layouts. I don't recall the instruction manual warning against use on a TMCC layout. Has anyone else had the same problem?
Much to my dismay, I checked with Lionel and learned they do not offer replacement windows for these cabooses. So I am needing to come up with another solution. I thought about purchasing a resin kit and casting a new part, but I am open to any suggestions.
