Thanks for your replies,bought the motor and dcc 80 as suggested,all worked fine,then motor jammed up solid,wouldn't even move manually.
Nothing to do with advice obviously,but made me wonder if anyone else has found these motors to be a problem?
Have sent it back to the supplier for replacement,and will see what happens with the new one.
When researching these particular point motors could not find any reviews or comments about them,which I find a bit stange??
