FYI - some of those #24s are "high-speed" switches, designed for full speed operation. I beleive the freight railroads run through them at 55mph, but on NJ Transit/Amtrak at the Keaney interchange, the passenger trains run thru at about 70+mph. I also believe they have movable frogs. There are 3 pneumatic actuators for the tie rods, and one or two for the frog, which closes to present a continuous rail for the passing track. Pete
