Video: A Transport for Wales Class 769 Flex unit (769003 - formerly 319003) is seen arriving and departing Cardiff Central on a series of test runs to/from Rhymney. This was my first time seeing a 769 on test up close, as they are finally starting to appear more out and about... mainly the TfW ones.
The Class 769 Flex trains are bi-mode or tri-mode units converted from former Class 319s with two diesel engines (MAN D2876) fitted under the driving coaches to give them some versatility. The diesel mode operations work by the engines powering the existing DC bus under the train in a similar way to the 319 third rail mode, this allows it to 'trick' the train to run in third rail mode in non-electrified areas.
Unlike the Northern 769s which will be bi-modes or the GWR ones will be tri-modes (not sure about ROG), the Transport for Wales units will not utilise their bi-mode capabilities as they will instead run on mainly non-electrified lines, hence why the pantograph has been removed from this unit. Finally, the batch for TfW are stopgaps and will be replaced by Class 756 FLIRTs in the future.
