CTA announced yesterday the purchase of 400 new rail cars that will roll into service in 2010. The cars feature live video security cameras, flat-screen monitors that display the train's current location, state-of-the-art diagnostic systems, and stain-and-smell resistant seat fabric. The new trains can run up to 70mph, unless you're in a beloved slow zone. Sadly cattle prods to move doorway loungers into the cars during rush hour will not be included.
