Sorry for the double post, but I waited too long and I can't edit my previous post.

I was wondering if you could add a small city power plant that many small cities had, and some still do, like Vineland, NJ.

If not a full power plant maybe a sub-station. This would give more of a small city feel of the '50s. That and possibly a gas pressure tank, the telescoping kind, that some cities had to keep the local natural/coke gas pressurized.The power plant and gas tank could be on one block, as the gas could supply the power plant. :=3
