A traction motor assembly includes a traction motor bearing that is equipped with a concealed and built-in lubricant reservoir. The traction motor bearing is disposed between inboard components and outboard components that are designed to provide annular clearances on either side of the traction motor bearing. These annular clearances may be exploited as a lubricant reservoir for the traction motor bearing. Lubricant can be added to the reservoir through ports disposed in the outboard cover. The disclosed design avoids the need to rely upon the lubricant reservoir used to lubricate the pinion and drive gears, which is subject to damage during normal rail operations.
