Hoping someone can help.  I'm not an expert by any means with my G scale Christmas train.  Get it out once a year and enjoy it during the holidays.  As a gift,I've received track over the last 5 years to the point that I thought I was ready to elongate my setup.  Used to just go in a circle around then christmas tree,, but now I've added a switch and crossing and plan to get enough track next year to finish the loops.

My problem is that in adding the switch and new track, the train won't run.  Gets no juice.  I've confirm all the track is setup correctly, and still nothing. What could I be doing wrong?  Does the track require a loop to be complete to operate?  Could the switch mess things up?

Any help is appreciated!

Brand new to this train hobby, but cannot get my brand new tender light to work.  It's brand new, straight out of the box...just set it up yesterday.  The "Night Before Christmas Model".  Any ideas on how to get this going?  The front light on the engine works great.  9V battery is inserted and all sound works as advertised....just the darn tender light!

Any help is greatly appreciated.
