Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
172 words
A high-speed, self-propelled railway train comprising a plurality of cars, means for supplying propulsive power for the train, each of said cars including a pair of bogies for independently supporting each car in rolling engagement with a track system, at least one of the endmost cars of said train being a traction car, said propulsive power means comprising prime mover means contained in said traction car, and on engineer''s compartment contained in said traction car for controlling operation of said propulsion power means and the starting, running, and stopping of the train, said prime mover means comprising, a single gas turbine engine of the variable output speed free running turbine type, variable speed ratio hydraulic transmission means connected to the output of said turbine, and fixed ratio transfer gear means for transmitting power from the output of said hydraulic transmission to at least one pair of wheels of a bogie supporting, said traction car whereby said train can be propelled at varying speeds from a standing stop by said free running turbine.
Claim 2
Dependent Claim
172 words
A high-speed, self-propelled railway train comprising a plurality of cars, means for supplying propulsive power for the train, each of said cars including a pair of bogies for independently supporting each car in rolling engagement with a track system, at least one of the endmost cars of said train being a traction car, said propulsive power means comprising prime mover means contained in said traction car, and on engineer''s compartment contained in said traction car for controlling operation of said propulsion power means and the starting, running, and stopping of the train, said prime mover means comprising, a single gas turbine engine of the variable output speed free running turbine type, variable speed ratio hydraulic transmission means connected to the output of said turbine, and fixed ratio transfer gear means for transmitting power from the output of said hydraulic transmission to at least one pair of wheels of a bogie supporting, said traction car whereby said train can be propelled at varying speeds from a standing stop by said free running turbine.
Claim 3
Dependent Claim
65 words
The invention defined in claim 1, wherein said hydraulic transmission means includes fluid clutch means and fluid torque converter means, the inputs thereof being connected to the output of said turbine, the outputs of the clutch and torque converter being connected to said fixed ratio transfer gear means, and means for selectively introducing fluid into and withdrawing fluid from said clutch and converter means alternatively.
Claim 4
Dependent Claim
144 words
The invention defined in claim 1, wherein both of the endmost cars of said train are traction cars of substantially identical construction, said engineer''s compartment in each car being disposed at one end of the car, the traction cars being oppositely disposed with respect to each other to position the respective engineer''s compartments at the respective ends of the train, said means for transmitting power from the turbine of each car to the respective pair of bogie wheels of each traction car including selectively engageable reversing gear means, whereby said train may be operated selectively in either direction at varying speeds from a standing start under control of an engineer in the engineer''s compartments of either traction car on power supplied by the gas turbine engine of either traction car, and on power supplied simultaneously by the gas turbine engines of both traction cars.
Claim 5
Dependent Claim
20 words
The invention according to claim 1, wherein said power transmission means also includes hydraulic braking means for decelerating the train.
Claim 6
Dependent Claim
25 words
The invention according to claim 1, wherein one of the cars of said train includes an area provided with facilities for the serving of refreshments.
Claim 7
Dependent Claim
25 words
The invention according to claim 1, wherein said train also includes at least one turbo generator means for supplying electricity for operation of the train.
Claim 8
Dependent Claim
16 words
The invention according to claim 6, wherein said turbo generator is contained within said traction car.
Claim 9
Dependent Claim
27 words
The invention according to claim 6, wherein said prime mover means and said turbo generator are contained within a common enclosed soundproof compartment in said traction car.
Claim 10
Dependent Claim
14 words
The invention according to claim 8, wherein said turbo generator includes an electrical alternator.
Claim 11
Dependent Claim
137 words
The invention according to claim 9, wherein said traction car is subdivided into a pluraltiy of compartmented areas comprising: an engineer''s compartment at one end of the car; a turbine compartment disposed adjacent said engineer''s compartment provided with an air inlet and filter for the turbines, exhaust gas system for the turbines and separate ventilating system for the compartment; a compartment for said power transmission system; a service corridor running alongside the turbine and transmission compartments and communicating with said engineer''s, turbine and transmission compartments; a compartment for baggage; a compartment for passengers adjacent said baggage compartment; a toilet compartment; a platform compartment at the other end of the car communicating with said passenger and toilet compartments and being provided with access doors for communication with the exterior sides of the car and with an adjacent car.
