Help to find the solution. Thanks

Train moves forward toward wagon A, coupling with it and moving it forward before stopping and uncoupling(1 move)

Train backs into wagon B coupling to it and then stops (2 moves)

Train moves forward toward wagon A and stops short (3 moves)

Train backs onto the side track and uncouples wagon B (4 moves)

Train moves forward coupling with wagon A and then stops (5 moves)

Train backs to the spot wagon B was originally in and stops to uncouple wagon A (6 moves)

Train backs through the tunnel and to the side track to couple with wagon B and stops (7 moves)

Train moves forward to where wagon A originally was and stops to uncouple wagon B (8 moves)

You need to return the engine to the siding.

Train moves forward to where wagon A originally was and stops but does not uncouple wagon B (8 moves)

Train backs into wagon A coupling it to wagon B then stops (9 moves)

Train moves forward past the side track and stops (10 moves)

Train backs onto the side track and stops to uncouple wagon A (11 moves)

Train moves forward to where wagon A originally was and stops to uncouple wagon B (12 moves)

Train moves forward through the tunnel and past the side track and stops (13 moves)

Train backs onto the side track into wagon A coupling with it and stops (14 moves)

Train moves forward off the side track and stops (15 moves)

Train backs to the spot wagon B was originally in and stops to uncouple wagon A (16 moves)

Train moves forward past the side track and stops (17 moves)

Train backs into the siding where it originally started and stops (18 moves)

You can shorten it by two moves if you: (most moves are the same)

01 - Train moves forward toward wagon A, coupling with it and moving it forward before stopping and uncoupling

02 - Train backs into wagon B coupling to it and then stops

03 - Train moves forward toward wagon A and stops short

04 - Train backs onto the side track and decouples wagon B

05 - Train moves forward toward wagon A and stops short

06 - Train moves around track, through tunnel, couples with A without stopping, moves onto siding coupling A to B and stops

07 - Train pulls both cars from siding and stops to decouple

08 - Train moves through tunnel, couples with B, stops and decouples A from B

09 - Train pulls B past siding (to original position) and stops to decouple (A & B are in original positions)

10 - Train moves through tunnel, couples with A and pushes A onto siding, stops & decouples

11 - Train moves through tunnel, couples with B and pushes B passed siding (to A start position), stops & decouples from B

12 - Train moves onto siding, couples with A & stops

13 - Train moves forward toward B but stops short

14 - Train moves A to B start position and decouples

15 - Train moves forward toward B but stops short

16 - Train backs into siding - stops and powers down.
