I have been searching the internet for months and found many examples of train tunnel builds and separately mountain builds. I would like advise of where to start to build a train tunnel inside of a snowy mountain. Currently I display my winter vintage only during the holidays on a large kitchen island. I have the Winter Holiday Train (10254) running around my winter village. While increasing my number of winter village sets, I am running out of room and am looking for a way to expand the display area. I want to build a train tunnel that looks like a snowy mountain that I can then add more Winter Village sets on top of the mountain. My village will then be two levels.
What is the right forum to post this type of question to get good advice?
