Abstract: Disclosed are various embodiments for rear railgear, pivot links, and pin-off systems. An example assembly including railgear, an attachment frame, a mounting bracket, upper and lower links is provided. The rail gear includes a pair of guidewheels, an axle, and an axle saddle; the attachment frame can connect to the axle saddle of the railgear; the mounting bracket is configured to attach to a vehicle; the upper link pivotably connected to the mounting bracket; and the lower link pivotably connected to the attachment frame, where the lower link is connected to the upper link via a pivot pin. The railgear can be secured in either the deployed or stowed position using various interchangeable pin-off systems, including but not limited to: a manual pin-off system, an air operated pin-off system, and a cable pin-off system. The railgear can also be secured in the stowed position using an automatic mechanical lock system.

Abstract: Disclosed are various embodiments for an automatic locking system for railgear. In an embodiment, the automatic locking system for railgear is an automatic mechanical locking system that can be incorporated into a front guide railgear assembly for use with conventional roadway vehicles. The automatic locking system can secure the railgear in a fixed orientation, either deployed for rail travel using the guide wheels of the railgear on rail tracks or stowed for highway travel such that the vehicle can operate using the conventional tires on a road, highway, and the like.

Abstract: Rail gear may facilitate a vehicle traversing on the rails of a railway. The rail gear may comprise a first rail guidewheel and a second rail guidewheel in rotatable connection with an axle. The rail gear may also comprise a first mount that is restricted from rotating with respect to the axle and a second mount that is configured to rotate with respect to the axle.

Abstract: An automated tribometer for measuring the coefficient of friction of the tread and gauge surfaces of railroad rail is disclosed. A tribometer is provided that is pushed in front of a high-rail vehicle, wherein during operation, the tribometer extends a rail test assembly to contact the surfaces of the rail. The rail test assembly has a rail testing wheel that is urged towards contact with the rail to be tested, and eventually contacts the rail, and lastly applies a known load to the rail. The testing wheel is then dynamically braked to slow the testing wheel to the point of creepage. The automated tribometer then can calculate the coefficient of friction of the rail.
