Although this is not a direct Bachmann quesation I hope to get an answer regarding buildings.
I purchased two buildings for a a N scale setup and they are both a diffferent size.
One is approx 25-30 % larger.  Are ther two n scale sizes???
PS I am using them on a Bachmann Yard Boss set.

Thank You for the information

Being new to N scale I am a little confused
I would like to add the EZ crossing gate to my round track, so I believe that I must add an equal straight track on the opposite side of the circle. The EZ Crossing gate
•Bachmann Product Number: 44879
list the length at 4 1/2 inches but the straight track sections come in 5 Inch sections. What is the proper proceedure?
Can I add just one section or do I need straight track before and after the gate?

Years ago there was a Bachmann Trim-A-Train Silver Star N Scale Train Set, that actually mounted to a Christmas tree and ran around it about 1/3 of the way down. I see that it is no longer made but wonder if the current models can be converted to run that way. How did  it attached to the tree?
