LOCO NOMENCLATURE has say 5 parts to it, e.g., WDM3A
1) W = Broad Gauge, Y = Metre Gauge, Z = Narrow Gauge , N = Narrower Gauge (as in some hill railways, Z = 2' 6" and N = 2')
2) D = Diesel, A = AC Electric, C = DC Electric , CA = AC+DC (Dual), B = Battery,
3) P =
...
more...
Passenger, G = Goods, M = Mixed, S = Shunter, M = DEMU/MEMU
4) Power Rating for Diesels = Number X 1000 HP, For Elec. = Version Number
5) Incremental Power Rating for diesels, for others Variants, Model Variations

WAP4 - WIDE A/C (POWER) FOR PASSENGER 4X1000HP...
WAM4 - WIDE A/C(POWER) FOR MIXED (PASS&GOODS) Transport 4X1000HP
Both are having same pulling power. WAMs have been converted into WAPs now a days where Goods trains have been now a days pulled using WAG's (Wide A/C for Goods)...
Admins- could anyone please update this in FAQ. (If already exists pls ignore)..

Mixed type locomotives:
WDM 1 (First mainline diesel electric locomotives used in India. Introduced in 1957. Imported from ALCO. Out of service now. 1950 hp)
WDM 2 (Most widely used and first homemade mainline diesel-electric locomotives in India. Original prototypes were made by ALCO. Introduced in 1962. More than 2700 have been made. Rated at 2600 hp)
WDM

2A, WDM 2B (Technical variants of WDM 2)
WDM 3 (Only 8 were imported. They used hydraulic transmission and are currently non-functional)
WDM 3A (Formerly WDM 2C. Another WDM 2 variant. It is not related to WDM 3. 3100 hp)
WDM 3C, WDM 3D (higher powered versions of WDM 3A)
WDM 4 (Entered service along with WDM 2. Prototypes designed by General Motors. Though considered superior to WDM 2 in many ways, these locomotives weren't chosen as General Motors did not agree to a technology transfer agreement. 2600 hp)
WDM 6 (Very rare class; only two were made; one is being used by Puttalam Cement Factory in Sri Lanka. Rated at 1200 HP)
WDM 7 (Fifteen of these locos were built from June 1987 through 1989, they were designed for branch-line duties, but they are now used mostly for shunting. Rated at 2000hp)
Note: No locomotive class was designated as WDM 5 in India.
Passenger locomotives:
WDP 1
WDP 2 (New class name WDP 3A. Dedicated passenger diesel locomotive. Entered service in 1998. Powerful locomotive. 3100 hp)
WDP 3 (This locomotives are actually prototypes of the class WDP 1 and never entered serial production.)
WDP 4 (EMD (former GM-EMD) GT46PAC, fundamentally a passenger version of the WDG 4 (GT46MAC). 4000 hp)
WDP 4B (EMD (former GM-EMD) GT46PAC, An improved version of the WDP 4, this is a more powerful version and has 6 traction motors, just like the WDG 4. Also comes with wider cabin to aid visibility and minor exterior design changes. 4500 hp)
WDP 4D (EMD (former GM-EMD) GT46PAC, This is basically a WDP 4B with twin cabs. Minor changes were made to the locomotive to facilitate the addition of a second cabin. This locomotive comes with LCD instrument display and toilet for the drivers. As of now, two units have been made and are expected to enter full-time service soon. 4500 hp)
Goods locomotives:
WDG 2 (New class name WDG 3A. These class is actually a technically upgraded form of WDM 2)
WDG 3B, WDG 3C, WDG 3D (Technical upgraded forms of WDG 2 or WDG 3A)
WDG 4 (New dedicated goods locomotives. These are General motors' GT46MAC models. First units were imported in 1999. They are numbered from #12000 upward. Local production started on 2002. 4000 hp)
Shunting locomotives (Also known as switching engines):
WDS 1 (First widely deployed and successful diesel locomotives used in India. Imported in 1944-45. currently out of service. 386 hp)
WDS 2 (currently out of service.)
WDS 3 (All locomotives of this class were rebuilt and reclassified as WDS 4C in 1976-78. 618 hp)
WDS 4, WDS 4A, WDS 4B, WDS 4D (Designed by Chittaranjan Locomotive Works. 600-700 hp)
WDS 4C (Rebuilt WDS 3 locos as mentioned above)
WDS 5 (Some of these locomotives are used for industrial shunting. A few are used on Indian Railways. Rated at 1065hp)
WDS 6 (Heavy-haul shunters made in large numbers for industrial concerns as well as for Indian Railways Rated at 1200/1350hp)
WDS 8 (Only five of these were made, and all were transferred to steel works 800hp)
Note: There is no electric shunting engine in India. Classes from WDS 1 to WDS 4D have hydraulic transmission. The WDS 4, 4A, 4B, 4C and 4D are the only still existing broad gauge locomotives with diesel-hydraulic transmission.
Diesel multiple units:
A few routes in India currently have Diesel multiple unit service. Depending on the transmission system they are classified as DEMU (diesel-electric transmission) or DHMU (diesel-hydraulic transmission). There are diesel railcar service in a few places known as 'railbus'.
DC electric traction
Note: These locomotives are, or were used only in sections around Mumbai which is the only location in India still using DC traction.The power operated is 1500V DC.
Mixed type locomotives:
WCM 1 ( First electric locomotives with the now familiar Co-Co wheel arrangement to be used in India. 3700 hp)
WCM 2 (520hp)
WCM 3 (600hp - Used in Kolkata , then transferred to Mumbai, Built by Hitachi)
WCM 4 (675hp - Also built by Hitachi)
WCM 5 (Built by Chittaranjan locomotive works to RDSO's design specifications. Auxiliaries by Westinghouse and North Boyce. Built in 1962, these are India's first indigenously designed DC electric locomotives. The first was named 'Lokamanya' after the Congress leader Bal Gangadhar Tilak. 3700 hp)
WCM 6 (A rare and highly powerful class. 5000 hp, only two were built. Now converted to run on AC power, class name changed to WAM 4)
Passenger locomotives:
WCP 1, WCP 2 (GIPR EA/1 and EA/2. Historically very important locomotives as these are the very first electric loco to be used in India. The first locomotive was named as Sir Roger Lumney and is currently preserved in the National Rail Museum, New Delhi. 2160 hp)
WCP 3, WCP 4 (GIPR EB/1 and EC/1, these are also among the earliest electric locos used in India)
Goods locomotives:
WCG 1 (GIPR EF/1. These are Swiss crocodile locomotives imported in 1928 from Swiss locomotive works. These are among the earliest electric locos used in India.The first locomotive was named as Sir Leslie Wilson and is currently preserved in the National Rail Museum, New Delhi. 2600-2950 hp))
WCG 2 (Designed by Chittaranjan locomotive works in 1970.)
AC electric traction
The 25 kV AC system with overhead lines is used throughout the rest of the country.

WAG 6A (Imported from ASEA and Hitachi. 6110 hp)
WAG 6B, WAG 6c (Variants of WAG 3A. All rated at 6110 hp)
WAG 7 (Very successful class. Designed by chittaranjan locomotive works. 5000 hp)
WAG 9 (Currently the most powerful class in India, rated at 6350 hp. Same design as WAP 7 with modified gear ratio. Designed by Adtranz, Switzerland.)
Dual (both AC and DC) traction
Note: These locomotives are, or were used only in sections around Mumbai which is the only location in India still using DC traction. They can run under AC traction too. The main purpose behind the manufacture of these type of locomotives was to provide transportation in and out Mumbai area without changing the engine.
Mixed type locomotives:
WCAM 1
WCAM 2
WCAM 3[1][dead link](Designed by Bharat Heavy Electricals Limited. 4600 hp under DC traction and 5000 hp under AC traction)
Goods locomotives:
WCAG 1 (Designed by Bharat heavy electricals limited. 2930 hp under DC traction and 4720 hp under AC traction)
Note:There is no dedicated dual current passenger locomotive in India, but in Mumbai area, there are some EMUs which can run under dual traction.
