Problem In Robe River, Engine's Won't Move

[fullbug]

Hi all, I'm new so I hope I wont tick anyone off with what may seem to be a stupid problem....
I'm learning Trainz 2004, on a Windows XP laptop, and everything has gone fine until I get to scenario 3 Robe River, where I'm suppost to uncouple, run around and couple at the other end, so I uncouple the engine no problem, but after that I cant move the engine anywhere, forward or backwords, doesnt matter, when I gun it smoke comes from the engine but it wont move, have made sure the brake is off ('A' on the keyboard' and tried restarting the scenario again but still the same thing, I'm stuck here, can anyone suggest anything?
I also tried hitting the other brake buttons as mentioned in the manual, 'Q, Z, A, E, D'

It has been a long while since I operated in '04 !
But I believe/remember that you have to position the Engine at a precise point on the siding , uncouple , then continue ?

I could be wrong , ---,DLR

Thanx, will try different positions before uncoupleling....

OK, not sure how I did anything different, but managed to decouple successfully.... But have a new problem, when I do my final step and couple with the waiting consist, when I touch the trains I get a collision message, and the game just jumps to the menu, I dont get it as I never do more then 1-2 KM when coupling with the consist....
