TFW Class 769 ride - Cardiff Queen Street to Caerphilly

Here is footage that my friend had filmed onboard a Transport For Wales Class 769 (ex Class 319) unit covering the section from Cardiff Queen Street to Caerphilly. The Transport For Wales Class 769s are diesel-electric multiple units which consist of 2 diesel generators in the front and rear carriages which power the electric traction motors in one of the unit’s trailer carriages. This part of the ride was filmed in the trailer carriage with the electric traction motors.
