21st March 2017 A recent 'odd ball' returning to use with GWR is Class 153 No.153305. The unit was previously part of the GWR fleet but was to be transferred to Northern, as part of this move the unit was sent to Long Marston to begin its colour change. However since then the unit has now returned to service with GWR and is currently wearing undercoat grey livery. It's ghostly appearance instantly gained it the nickname 'Casper'. On the 21st March 2017 Casper can be seen at Taunton ready to depart with the 2U26 17:06 Taunton - Cardiff stopping service. (Photo: Thomas Courtney)
