The Cab04 and Cab05 are our most popular engineer cabs. Both cabs feature easy selection of locos/consists, single button operation of all decoder functions, momentary HORN button. Selection and control of individual or entire routes through turnouts (via the MACRO key), and our unique OPTION button that can be programmed to act as any button you wish, even those found on a much larger cab. The Cab04pR, Cab04eR and Cab05 R are available as radio equipped.
