I have a "Bachmann Big Hauler".  Its called the "Gold Hill Express" and I purchased about 8 or 10 years ago I'm thinkin'.  The Item No. on the box says 90090.  Its a 4-6-0 locomotive.  The headlamp is inoperative.  When I set the train up for X-Mas this year, the light was working but then it went out.  Guess it died.

Can someone suggest where I may get a new one and most importantly, how do I replace it?

Also, where can I get some of the smoke liquid.

I'm the "set the train up for Christmas" guy and therefore not a great hobbiest so any help would be appreciated.

TIA

Jim
