We have a Train Station Set, but this built is so loose and comes apart so easily thus it is really hard to move/play/connect to other parts. Is there some product like temporary LEGO glue to stick things together in the span of months to a year, and can come of easily with some dissolvent?
P.S. I searched on StackExchange or Reddit, "DO NOT GLUE" does not fit my scenario.
EDIT: Add the picture. We assembled it, but the roof/pole/base falling apart easily simply when connecting with more rail tracks.
