I know this happens on more than one occassion in Chicago as well. There is an interesting article in Trains, I think, concerning RS-3s and how they were great with handling that kind of pull. It would be interesting to know the grades on some of those flyovers. Wish I could be of more help. Gabe Reply ChrisBARailfan Member sinceApril 2005 From: Kansas City, MO 100 posts Short grades and flyovers question Posted by ChrisBARailfan on Thursday, May 5, 2005 11:22 AM I live in Kansas City and BNSF / UP and others have built two massive fly-overs and bypasses. I have been over one of the flyovers and its approach is short, but very steep. It looks almost like a highway on ramp. I am not sure of the angle, but seems steep for a railroad. My question is if the length is short does incline rate not really matter? I ask this because I saw a BNSF transcon stack train stopped on the approach awaiting a signal. He had 4 C9-44Ws and when he got the green it was almost impossible to get going, the engines were definitly in run 8 and the ground was almost shaking underneath. Is this bad design to put a signal on the approach or is it just an annoyance to the engineer? Thanks, Chris Reply Join our Community! Our community is FREE to join.
