I completely disagree. The only way to truly understand why the trains have not been refurbished is to ride it. Honestly, the old look and feel of the trains, with their leather seats, and leather cushoned lap bars are one of best parts of this ride. Not only that, but the painting on the outside of the trains gives it a great classic feel as well. Just leave it how it is, and don't try to modernize it... It is meant to look old and run down, anything else just wouldn't feel right.
