Used Tower 55 HO T55 EA-0502-2 ES44AC Southern Pacific #383 w/DCC and Sound by DigiTrax w/Box

This is a Used Tower 55 HO T55 EA-0502-2 ES44AC Southern Pacific #383 w/DCC and Sound by DigiTrax.
The model comes in the original box that has some shelf wear.
There is no owner's manual, but there is a parts diagram.
It seems to be missing the snow plow and the little red hose piece on the pilots.
Both of the couplers will not center themselves and the rear coupler will not open by the brake hose as it is stuck.
We did test the model conventionally and it runs, but sometimes loses power.
The horn also contiues to blow repeatedly. Might be because it's being run conventionally and not with DCC.
Plays sounds and has operating headlights.
The ditch lights also flash.
Looking under the shell, one of the power plug connectors to the board is broken loose. This could explain why the model would loose power, as only one of the trucks is picking up track power.
The paint and lettering is quite nice with some paint wear on the railings.
Overall is a pretty decent looking model with fine detailing.
