A traction motor housing 3 has a motor chamber 6 for receiving an electric traction motor 4, and a transmission chamber 12 for receiving transmission apparatus 5 drivingly connected to the electric traction motor. A sump 17 is provided to collect a lubricant 16, and the sump is fluidly connected to the transmission chamber. To prevent lubricant flowing from the transmission chamber into the motor chamber, a partition 22 is provided between the chambers, but a lubricant return means 23 provides for returning lubricant from the motor chamber to the sump, via an inlet 24 and an outlet 25. The lubricant return means extends away from the partition into the transmission chamber and/or the sump, and in use, reduces or inhibits the flow of lubricant from the sump into the motor chamber.
