Nice one buddy, it looks like you may need some new controller and maybe some new track as its not really obvious what track you got there. But generally speaking that's probably the cheapest part as you can just buy a cheap starter set to get all that.
I would say the engine alone is easily worth $30 if it runs right, the other rolling stock a couple of bucks each if cleaned up, so no matter how you like to look at it you've easily got your money back even if you just sold it all on

Happily collecting things all my life...
