This Bachmann HO Scale Siemens SC42-DM Dual Mode with WowSound and DCC is based on the fleet of regional and commuter diesels which can also operate on third-rail electric which is required in certain locations. The model is a variant of the popular SC-44 Charger delivered to Amtrak and several commuter railroads beginning in 2017. Built in Siemens Mobility's Sacramento facility, the 4,400 horsepower SC-44 Chargers have become popular with many commuter lines. Amtrak later ordered the long-distance version of the diesel designated the ALC-42. VIA Rail Canada ordered a version of the diesel as well, designated the SC-42. Bachmann's SC-44 has been developed using original design documentation and employs prototype field recordings for maximum realism. Features include a TCS WOWSound CD-quality 16-bit 44,100Hz decoder with Audio Assist(R) for easy configuration without CVs, and a Keep-Alive(R) device for uninterrupted operation, even over dirty track. The WOWSound diesel-electric locomotive package includes an authentic horn, bell, prime mover, startup/shutdown, compressor, cooling fan, coupler close/release, brake release/application, crew alert, grade crossing quill, station announcements, and more. It also includes dual flywheels, a can motor, E-Z Mate(R) knuckle couplers and RP-25 wheels for operation on Code 70 and larger rail. The Siemens SC42-DM Dual Mode is one of many Bachmann HO Scale locomotives.
