"Class" train....

Nothing really spectacular, but I spotted this one just east of Topeka... what caught my eye was that the entire train was all KLine containers. Before I could get back to the car, I caught this last shot of a west bound....

On UP those are known as "Z-" trains, and they are accorded priority on the rails.

Great shots Bob. I love the UP and it looks like they are covering some serious ground in your pics.

Z trains are just "hot" intermodal, usually used for UPS trains. Thats probably just an I train.
