The two hired steam railmotors were GWR nos. 1 & 2, which had been built in October 1903 for £3477-4-0d () for the pair; the LVR hired them for £420 () per year, again for the pair. They had an axle loading of , and since the line had been designed for a maximum axle load of , the bridges needed to be inspected with both railmotors upon them before they could be approved for use. When they were temporarily returned to the GWR for maintenance between October/November 1904 and January/February 1905, their replacements were nos. 19 & 21, which had been built in July/June 1904. In July 1905, one of the railmotors covered a duty which on Mondays to Saturdays began at 07:45 and ended at 19:52, covering ; it was supplemented on Thursdays and Saturdays by the other which began at 12:40 and finished work at 17:11, covering . On Sundays just one railmotor was required, between 10:00 and 14:00. The highest speed attained by the railmotors was , with an average speed of . One railmotor could handle a tail load having not more than 28 wheels.
