Perfect for use at railroad shops, short lines and industries, this tiny locomotive has been designed with performance in mind. DCC Versions include an ESU LokPilot non-sound decoder with a built-in capacitor to maintain performance during brief power interruptions. The prototypes have been in service since the 1920s through the present day with several now in museums. Painted, unlettered locos include decals with Cornerstone(R) industry logos, numbers and more.
