2012 also saw the introduction of the special hybrid train service, where diesel locomotives were made to pull these decrepit Class 82 bodies with functional doors, lighting and A/C（short form for air conditioner). Since the power transformers and power pick up systems could not be replaced, the company elected the use of additional diesel generators affixed on hopper wagons to power up the EMU. In effect, it reduced the role of these sets to nothing more than unpowered passenger coaches, but its use still had better convenience than compared to KTMB's traditional unpowered coaches, which typically tend to be those specifically designed for long-distance intercity use, i.e. the doors were narrow and few, with limited standing space while having an open emphasis on comfortable seating. As mentioned the Class 82 is not like that, and was design specifically to meet its role as a sub-urban commuter and gracefully step up to its role as a commuter rail wagon.
