One of two similar units, this example has a protective roof whereas No.24 Betsy is open-topped; it saw extensive use on both the railway and the electric line on departmental duties and was overhauled off-site in 2021 it returned to the railway with a replacement cab unit, at which time the fleet number and name were applied for the first time making the unit canonical within the historical fleet numbering sequence.
It was built for use at National Coal Board depot at Kilnhurst in Yorkshire and arrived on the island in October of 1996, being overhauled and painted yellow. It was used during the short line workings to Santon Station during the I.R.I.S. Scheme works to shunt stock and also spent some time on the electric railway. Its most recent use was in the winter of 2022/2023 used in conjunction with lineside flailing with Well Wagon No.2, currently stored at Castletown Station.
Carrying an all-over blue scheme on delivery, it was painted yellow by Derby Castle Depot staff when in use on the electric line, with red chevrons and stenciling added, being painted into the standard departmental dark green upon return and fitted with the post-war crests on the cab sides. It was taken off-island for a refurbishment in 2022, returning with a rebuilt drivers' cab and new windows with protective cages covering the glazed openings. Also fitted with an air-operated chime whistle.
