For some reason now my speed control doesn't make the train go any faster & ther directional switch has no effect at all.   The headlight is very dim, & the train moves very slow.

I've check the track carefully, & there is nothing obstructing it.

The engine appears fine.


We've only had this set about 10 days or so...


I can't figure out what's wrong...


Any & all help & suggestions are most appreciated!
