The last WAP 4 locomotive of IR rolled out with "Mid-Mounted" headlamps, # 22310 from Howrah looking fresh & rejuvenated after undergoing periodic overhaul (POH) at Eastern Railway's Kanchrapara Workshop (KPA). Since the loco hasn't visited Dahod Workshop for MTR till now, it has retained its original looks including the windscreens. As per the current guidelines for the schedule of WAP 4 locos, the next POH will be approximately after 9 years when it may go for MTR.
