This loco used to be an IR WDM-2. In 1969 this loco was appropriated by Pakistan and became part of the PR fleet. It was initially numbered 3770 and later renumbered to 4621 to better conform to PR's Alco number series although it's not exactly the same model as the other Alcos in that series. As late as 2000 this loco was hauling trains regularly and was homed at Rawalpindi. PR staff nicknamed the loco 'Indira Gandhi'. The loco's original IR road number is not known.
