As Dave Bittner pointed out to me on Twitter, there is/was a rail line going into Columbia East. While some may point to this as a sign that train service to TC would be unfeasible, I would dispute this assertion by looking at the economics of the old rail line and the new rail line. First, the old rail line was designed to be industrial rather than for the transportation of people. It was built during a time when rail was being supplanted by trucks and this line's failure is a symptom of that. With the increase in the cost of gas in addition to people's increasing frustrations with traffic, a train service to TC would make sense. There was also the older argument against trains in that it would increase crime at the mall, particularly theft. Well, let's look at the potential theft v. the economic impact of saving up to an hour a day off of people's commutes. I don't have those numbers since no one has done a study yet, but just pure supposition would probably support my argument.
