^ I thought I read somewhere that the engines at SFOG were diesel powered engines. Im going to have to check and see.
Additionally, did anyone get out to the park yesterday or today? Any progress on the 3rd lap?
Digging deeper we were both correct, originally built as steam and converted to diesel hydraulic. The motor is in the tender. Here's is the topic I found: http://www.rypn.org/forums/viewtopic.php?f=1&t=7438
I get why they did it, much cheaper cost. Concerning the fire, it sure looked like the cab was on fire which wouldn't be surprising since the tender is right behind it. Either way it's the media so there's that.
Edit: In reference to TNT, I appreciate that those parks still run steam. As I mentioned it is extremely expensive both in maintenance and training/staffing. I always make a point to try to ride the railroads at both parks. (At St. Louis it is a life saver.)
