Not completely sure if this is the right place to ask, but I recently picked up a second hand older Bachmann 08 from Hattons for a pretty good price, however it just arrived in the post today and only runs, quite noisily, in one direction, and won't budge in the opposite.
I'm a bit wary of dismantling it, as my usual subjects are 1980s vintage models, that are a fair chunk less complex and detailed. (though I will once I know what problems I'm looking for)
Any ideas what could be causing this?
