I have the Lionel 6-25419 Southern Pacific Stationsounds diner which works fine on a seperate piece of test track making the rail clatter sounds and conventional sound commands from an MTH Z-4000 transformer. The club transformer is a MTH Z-4000. I am not sure in the following videos if it is making just the grind/wheel flange sounds with no interior lights or if that is the Shasta Daylight RPO with a side frame on it's way out making that sound? I have the volume pot all the way up with the run/program switch set to run and the light switch on. Here are a couple of videos with the Stationsounds diner behind the RPO to see if anyone can tell?
