When my 4014 MTH Big Boy was acting up I got out my Signal Tester and learned four out of seven MTH 70' passenger cars kill the DCS TIU signal in my UP Steam excursion consist. Why?
The cars are Vista Dome #7004 from Set 20-65116, Coach #5437 from Set 20-65116, Coach #5488 similar to #5437 (unknown MTH set or number), and Potrero Observation from Set 20-65227. The first three were cataloged in 2007 probably and the Observation car in 2013.
What must be done to have these cars in my DCS consist?
