I have a Wonderland Express (#25001) that i want to incorporate in my permanent Christmas village display.  In order not to redo the entire setup (everything was designed around a smaller battery operated train), my only option is to make a long oval around the village.  The current kit will make a 36x54 oval & i need at least 36x76 or 80.  The kit has the Bachmann 46605 power supply/controller.
my question is, would this power supply handle the additional length of track ok or would i need a larger one?
Thanks for any advise as friends/neighbors dont want me destroy/redo the hard work i put in the current setup.
Happy Labor Day,
