Ben,
the sad thing about the Weaver Troop sleeper cars is the zinc rot only occurs in some production runs. I have two express cars I purchased that were in the first release. Those two cars have been Soldiering on for years.
Another problem with Weaver Troop sleepers is the trucks. The side frames are easily broken from the bolsters. Atlas redesigned the trucks and this problem also appears to have been corrected by Atlas.
While we’re on the subject, I need a light strip for a Troop sleeper. This part has not been available from Atlas. I purchased an undecorated Weaver Troop sleeper years ago that was missing its light strip.
If anyone has a junker Weaver Troop Sleeper with a light strip in it please let me know.
Thanks
Richard
