hi

i got a Bachmann Trains Deluxe Thomas and Friends Special Ready-to-Run HO Train Set for my son from the US, im in the UK.

I purchased a Hornby PSU which fitted just fine, its 15V DV i believe

problem is the controller only works in one direction, its a blue controller with a direction switch, but it only seems to work when switched to one side only

i got another replacement off amazon and it does the same thing, have i been unlucky twice or is it something else

ive taken the train to my fathers hornby track and the train goes both directions no bother, a multimeter across the track only shows voltage when switch in the working side.

any clues?

thanks
scott
