Narrow-gauge locomotives of India
This is a list of all narrow-gauge locomotives that have been or are being operated by Indian Railways. IR has decided to convert all routes except the heritage one to the nation-wide standard 5 ft 6 in (1,676 mm) gauge, under Project Unigauge. So narrow gauge locomotives are becoming rarer and rarer.
General
- ZDM-1: This locomotive was built by Arn. Jung. These were called the class DZ on NR (Kalka-Shimla Railway).It is identical to NDM-1 class with 2'6" gauge. Only four of these locos were regauged to 2'0" gauge and converted to NDM-1 units. When the ZDM-3 locos were available in (1972-1982). The fifth loco NR #704, was at Pragati Maidan in New Delhi. Where it was used to haul a short train of aluminium-bodied coaches on a 1.5km figure-8 track at a exhibition centre. Loco numbers doesn't written on the body of the loco.
- ZDM-2: This is a narrow gauge locomotive with 2ft 6in wide gauge.These loco were mainly used in Nainpur-Gondia section narrow gauge route.Now all the locomotives are retired/withdrawn from service.
- ZDM-3: This is a narrow gauge locomotive with 2ft 6in wide gauge of Indian Railways.This locomotives can be found on the routes of Kalka-Shimla route and Kangra Valley route.
- ZDM-4: This locomotives were built by CLW and they are the modified version of ZDM-3 class with an extra axle to reduce axle load (1-B-B-1 bogies). But this extra axle cause wheel slip.This locomotives can be found on routes like Kangra Valley,Nagpur narrow gauge route and raipur narrow gauge route.
ZDM-4A: This is a variant of the ZDM-4 loco. This loco was used in Barsi Light Railway. These 1-B-B-1 locos have a 700hp power-pack. In 1996 one of this was sent to Nepal Jayanagar Janakpur railway line.
- ZDM-5: This locomotive was one of the powerful narrow gauge locomotive of the world .This locomotives can be found on routes like Paratapnagar narrow gauge and Dhaulpur narrow gauge routes. Four locos of this class was sent to work on Jayanagar Janakpur railway in Nepal in 1994.
- NDM-1: This is a articulated locomotive with two prime movers. But in case of uphill travel it uses its both engines and in case of downhill it uses one engine on Neral-Matheran line. It was originally intended to be used in Kalka-Shimla route. When Kalka-Shimla route was regauged ZDM-3 was obtained for that route.
- NDM-5: This locomotives are used on Central Railways Gwalior narrow gauge route. This locomotives are based on another narrow gauge locomotive called ZDM-5. It has been equipped with dual brake system.
- NDM-6: This locomotive was originally intended for Matheran Light Railway but due to some reason it was then allocated to Darjeeling Himalayan Railway. Only 6 of these locomotives have been made and all are in service on Darjeeling Himalayan Railway.
- NBM-1: This locomotives were used on Central Railways Gwalior narrow gauge route. This are the battery electric locomotives. Only three units were built in 1987.

gollark: But then you wouldn't get alerts which are directly relevant to you.
gollark: It's not really.
gollark: Funnily enough, I *want* to live in a city and currently live an annoyingly long distance from the nearest one. Short enough that I still commute there for school, but long enough that it takes a while.
gollark: At least if the stay at home thing is cancelled *somehow* the government has already said they're cancelling exams this academic year.
gollark: It's a continuation of a conversation in here.
