No. Between 7th Avenue and the portal, there's a downgrade of 3.1% which runs for about 1600 feet.Keying by two reds after the 4th Avenue portal would put Abbott's train on that grade going up, as well as clear of a curve, allowing him to see the oncoming runaway. While there is, in the northbound direction, a brief 2% upgrade south of 7th Avenue, there is another long 3% downgrade south of that. This means that that runaway could have started from the area of signal B3-633 and picked up sufficient speed from there. |
