Talgo’s pendular suspension lowers the carbody’s center of gravity and relocates its center of rotation, all enabling Talgo cars to take curves faster without causing excessive passenger discomfort due to the centrifugal force.

Rear-end locomotives on distributed power trains may run with or without flashing rear end devices. Steve Schmollinger Q I see distributed power on BNSF freights inbound into San Diego, and some have flashing rear end devices attached to the coupler at the end locomotives.

Q How does BNSF’s Network Operations Center in Fort Worth, Texas, control BNSF trains when they share tracks with another railroad, such as the route over the Tehachapi Pass? Union Pacific owns the trackage and allows BNSF trackage rights. On average, BNSF sends three trains over the pass to UP’s one. Does the BNSF Operations […]
