Back when Houston decided it no longer really wanted to be the Space City anymore (The reasoning behind which still escapes me to this day), we rechristened ourselves the Bayou City and also got really into trains. When Enron Field opened the old Union Station location they went in for a distinctly train station homage, and the engine along the stadium walls celebrating the frequent home runs has become a beloved fixture.
My daughter loves trains. Most kids do. And the good news is that if you want spend a couple of days chugging along on choo choos with your kids there are some really first rate ways to do it.
