Since 1965, HOTSTART has been helping railroads stop idling and save money. By equipping locomotives with a HOTSTART layover heater that will keep the engine above 100°F, the locomotives can be shut down instead of left idling for hours and still have an easy restart even in freezing environments. This reduced idling means fuel savings that directly impacts your bottom line. Now, over 4,000 HOTSTART locomotive systems are in use today with BNSF, MRL, Genesee & Wyoming and Cedar Rapids and Iowa City Railway.
