The Downtown Albuquerque Rail Runner and Amtrak Stations are currently located on a viaduct with the platforms directly above the Alvarado Transportation Center. One of ABQ Ride's (the local bus systems) main bus stations downtown. Amtrak and Rail Runner don't actually share the same platforms, but are both on the same rail line. Amtrak's simple side platform has another concrete platform just across the closest side track is due south of the Rail Runner platform that is also only a side platform that has the typical Rail Runner platform features of a pueblo style platform shelter and the Tall post with the station name symbol and bird at the top of it. Rail Runner has no station building of it's own (although the Transportation Center does have simple computer printouts of its schedule). The Amtrak Station is shared with the greyhound station that is also here. Its ticket counter is across from the Greyhound one. The Amtrak station's location within the greyhound station is extremely recent. I saw the closed former stand-alone Amtrak station in it's own building within the transportation center.
