Switching device configured for operation on a conventional railroad track
First Claim
Patent Images
1. A switching device configured for operation on a conventional railroad track system with a first rail and a second rail supported in a spaced relationship, the switching device comprising:
- a main wheel supported on the vehicle in position to abut and ride upon a top surface of a rail head as the vehicle traverses the conventional railroad track system;
a side roller bearing movably supported on the vehicle, the side roller bearing movable between a guide position, in which the side roller bearing abuts and rides upon a first one of a generally-vertical side surfaces of the rail head as the vehicle traverses the conventional railroad track system, and a clearance position, in which the side roller bearing is displaced away from the guide position; and
a spring operatively connected to the side roller bearing, the spring biasing said roller bearing toward said guide position.

Abstract
RailPods are an alternative personal rapid transit system that operate on and utilize existing railroad infrastructure. RailPods are one to two passenger vehicles that travel on one rail of a traditional railroad track. RailPods provide on-demand transportation to cities and towns where rail exists or can be built.

2. A switching device configured for operation on a conventional railroad track system with a first rail and a second rail supported in a spaced relationship, the switching device comprising:
-
a main wheel supported on the vehicle in position to abut and ride upon a top surface of a rail head as the vehicle traverses the conventional railroad track system; a side roller bearing movably supported on the vehicle, the side roller bearing movable between a guide position, in which the side roller bearing abuts and rides upon a first one of a generally-vertical side surfaces of the rail head as the vehicle traverses the conventional railroad track system, and a clearance position, in which the side roller bearing is displaced away from the guide position; and a linear actuator operatively connected to said switching device, said linear actuator being operable to raise and lower said switching device.

3. A switching device configured for operation on a conventional railroad track system with a first rail and a second rail supported in a spaced relationship, the switching device comprising:
-
a main wheel supported on the vehicle in position to abut and ride upon a top surface of a rail head as the vehicle traverses the conventional railroad track system; a side roller bearing movably supported on the vehicle, the side roller bearing movable between a guide position, in which the side roller bearing abuts and rides upon a first one of a generally-vertical side surfaces of the rail head as the vehicle traverses the conventional railroad track system, and a clearance position, in which the side roller bearing is displaced away from the guide position; and a ramp supported adjacent the side roller bearing, the ramp being positioned to impinge upon rail structure at a junction of the conventional railroad track system and to cause the side roller bearing to move away from the guide position and toward the clearance position while the switching device is traversing the junction.

4. A switching device configured for operation on a conventional railroad track system with a first rail and a second rail supported in a spaced relationship, the switching device comprising:
-
a main wheel supported on the vehicle in position to abut and ride upon a top surface of a rail head as the vehicle traverses the conventional railroad track system; a side roller bearing movably supported on the vehicle, the side roller bearing movable between a guide position, in which the side roller bearing abuts and rides upon a first one of a generally-vertical side surfaces of the rail head as the vehicle traverses the conventional railroad track system, and a clearance position, in which the side roller bearing is displaced away from the guide position; and an opposing side roller bearing movably supported on the vehicle, the opposing side roller bearing being movable between a guide position, in which the side roller bearing abuts and rides upon a second one of the generally-vertical side surfaces of the rail head opposite the first one of the generally-vertical side surface of the rail head as the vehicle traverses the conventional railroad track system, and a clearance position, in which the opposing side roller bearing is displaced away from the guide position to prevent interference of the side roller bearing with structure of the corresponding rail as the side roller bearing traverses a junction of the conventional railroad track system.

5. A switching device configured for operation on a conventional railroad track system with a first rail and a second rail supported in a spaced relationship, the switching device comprising:
-
a main wheel supported on the vehicle in position to abut and ride upon a top surface of a rail head as the vehicle traverses the conventional railroad track system; a side roller bearing movably supported on the vehicle, the side roller bearing movable between a guide position, in which the side roller bearing abuts and rides upon a first one of a generally-vertical side surfaces of the rail head as the vehicle traverses the conventional railroad track system, and a clearance position, in which the side roller bearing is displaced away from the guide position; and a ramp supported adjacent the side roller bearing, the ramp being positioned to impinge upon rail structure at a junction of the conventional railroad track system and to cause the side roller bearing to move away from the guide position and toward the clearance position while the guide shoe is traversing the junction.

6. A switching device configured for operation on a conventional railroad track system with a first rail and a second rail supported in a spaced relationship, the switching device comprising:
-
a main wheel supported on the vehicle in position to abut and ride upon a top surface of a rail head as the vehicle traverses the conventional railroad track system; a side roller bearing movably supported on the vehicle, the side roller bearing movable between a guide position, in which the side roller bearing abuts and rides upon a first one of a generally-vertical side surfaces of the rail head as the vehicle traverses the conventional railroad track system, and a clearance position, in which the side roller bearing is displaced away from the guide position; and an opposing side roller bearing movably supported on the vehicle, the opposing side roller bearing being movable between a guide position, in which the side roller bearing abuts and rides upon a second one of the generally-vertical side surfaces of the rail head opposite the first one of the generally-vertical side surface of the rail head as the vehicle traverses the conventional railroad track system, and a clearance position, in which the opposing side roller bearing is displaced away from the guide position to prevent interference of the side roller bearing with structure of the corresponding rail as the side roller bearing traverses a junction of the conventional railroad track system.
