Amtrak upgrades to high-speed rail system
In the first of what is hoped to be many upgrades in railroad tracks, Amtrak announced that 45 miles of its track in southwest Michigan was converted to a new high-speed rail system.The new track, laid between Kalamazoo and New Buffalo, runs along Amtracks Detroit to Chicago corridor.The upgrade, developed by Harmon Industries Inc. of Blue Springs, Mo., allows trains to surpass the previous limit of 79 mph set by the Federal Railroad Administration and reach 90 mph, said Jeff Baker, product manager for the system.It combines an onboard computer on each one of the locomotives with information from the wayside signaling system, he said.
