Changes
Minor externally visible changes common across the whole line include the following:
- Modified trucks with damping struts. Four-axle trucks have damping struts on two diagonally opposite corners. Six-axle trucks have them on the center axle.
- Six axle trucks with all traction motors pointing towards the center. This improves the truck's factor of adhesion but also increases each truck's overall length. The locomotive's frame was lengthened as a consequence. These were the HT-C trucks which were employed for the next 20 years. The older Flexicoil trucks remained a seldom-selected option.
- Engine water level sight glass on the rear upper right-hand side of the long hood.
- Battery boxes in front of the cab have bolted down covers, rather than hinged.
- Equipped with both high and low positions for rear classification lights, one set being blanked.
- Cab roof extends slightly beyond the cab rear to accommodate the larger electrical cabinet.
