Great-looking installations in this thread. I don't have any MTH buildings, mine are all Dept. 56 and Lemax. So I was very reluctant to drill any holes into Victoria Station. Instead, I used a half-inch thick square of plexiglass, glued it to the deck of the layout, then glued the support towers to the top of the plexiglass and used it as the support. The wiring runs down between the back of the building and the front of the plexiglass, with holes drilled into the deck of the layout, where the wires are connected underneath. So, installed in the back of the structure, no drilling was required and it's held up for years and years. I love Miller Engineering signs.
