I am installing a switch for a heater element on a DC (analog) locomotive.
What is the common post used for with this type of switch?

I am assuming i can just solder to pin 1 and 3 and be done.  Please let me know

I have had this train for a couple weeks and the smoke stack is melting.  We always use fluid when running this train!  What the heck?

Hello, i just acquired a New, in the box Jupiter 4-4-0 Locomotive.
Could anyone tell me what I should do before firing her up?  She is brand new, never driven, old stock

Thanks

I have a new old stock Model Power and Bachmann power pack. Both are AC/DC
They cut out after about a 1 minute or two of use.  My other power packs work fine (one is the same Bachmann)

I am wondering what the deal might be!

Thanks
