Abstract
Abstract A train or railway car and the like powered by a gas turbine having an auxiliary electric motor selectively connected to a gear train to drive the car for propelling it in and through areas of operation in underground or urban areas, thus avoiding causes of pollution either at start-up or driving operation, and for allowing a thermal engine to propel the car through high speed operations.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
142 words
In a railway train of the type wherein at least one of the cars comprises a power car which includes prime mover means for propelling said train, the combination including a single free running gas turbine engine contained in said car, an electric engine contained in said car to be energized from a source exterior to said car, gearbox means including reversing gear means for mechanically transmitting motive power to the wheels of at least one of the bogies of said power car, and coupler means for selectively coupling said gas turbine engine and said electric engine to said gearbox means to transmit power selectively from only one prime mover means during any particular operational period, whereby each of said engines may selectively directly supply power to the same bogie wheels for propelling said train through the coupler means in either direction.
Claim 2
Dependent Claim
142 words
In a railway train of the type wherein at least one of the cars comprises a power car which includes prime mover means for propelling said train, the combination including a single free running gas turbine engine contained in said car, an electric engine contained in said car to be energized from a source exterior to said car, gearbox means including reversing gear means for mechanically transmitting motive power to the wheels of at least one of the bogies of said power car, and coupler means for selectively coupling said gas turbine engine and said electric engine to said gearbox means to transmit power selectively from only one prime mover means during any particular operational period, whereby each of said engines may selectively directly supply power to the same bogie wheels for propelling said train through the coupler means in either direction.
Claim 3
Dependent Claim
