PRR Streamlined K4 N53951 with Econami DCC

[spinalzo]

Hello,
I have a PRR Streamlined K4 N53951 with Econami DCC that makes sounds but does not move.
1) Where can I get a replacement manual - my original has been lost.
2) Things were functioning well until I added some track and electrical feeds, that is when the sound kept working but the engine stopped moving.
I am a novice N scale model railroader.

Any insight will be greatly appreciated.
