Abstract
An articulated railway car includes end to end body units with adjacent ends supported on a wheeled truck and interconnected in articulated relation. Side bearing arrangements disposed on opposite sides of the articulated connection include relatively interengaging and telescoping bearing elements designed to prevent torsional twisting movement of the body units about a longitudinal axis.

In an articulated railway car including a pair of car body units arranged in end to end relation,
- a truck underlying adjacent ends at said body units for supporting the same and including a pair of wheeled axles positioned respectively under the adjacent ends of said units,
- means projecting outwardly from the adjacent ends of said body units and being interconnected to provide a vertical articulated connection for said car;
- the improvement of a side bearing arrangement supported on the adjacent ends of said body units on opposite sides of said articulated connection, said arrangement comprising,
- first male bearing element projecting outwardly from one of said adjacent ends,
- second female bearing elements projecting outwardly from the other of said adjacent ends,
- said bearing elements being in telescoping sliding engagement with one another and interconnected to prevent rotation of one body unit with respect to the other body unit about a longitudinal axis of said car.
