2. Basic Information about CLW
Site located in Sept
1947,Construction
started in May 1948.
First loco completed
on January 26,
1950.
Steam locomotive
produced during
1950-1970.(Total
no.-2351)
Diesel locomotive
produced during
1967-1993(Total no.
- 842)
First CLW built
WCM-5 1500v DC
electric loco
LOKMANYA in 1961.
On 16 Nov 1963,
first 25kv ac WAG-1
“BIDHAN” was
flagged off.
From 1967, CLW
started production
of Traction motors.
On 30 Jan 1972,
WCAM-1 AC/DC dual
“vallabh” was
produced
First three phase
loco was the 6000hp
WAG-9 1998
“NAVYUG”
CLW gets power
supply from DVC
through 33kv line.
Total demand is
nearly about 11.5
MVA
On 29th April,1998
Flagging off of
2500th Electric loco
SWARNA ABHA
takes place.
On 26th April, 2002,
ISO-14001
certification is
awarded to CLW by
IRQS.

20. ADVANTAGES OF ELECTRIC
LOCOMOTIVE
• Electric engines do not produce much heat
and noise.
• Electric engines are therefore easier to
maintain whereas the moving parts of a diesel
engine require constant maintenance.
• The simple nature of the electric engine
makes them efficient and powerful.

21. ADVANTAGES OF ELECTRIC
LOCOMOTIVE
• Electric engines are light weight, constituting
only motors and wheel axles, and have almost
no moving parts.
• Do Not Produce Smock.
DIESEL
LOCOMOTIVE

22. ADVANTAGES OF THREE PHASE LOCO
over DC LOCO
• It Require little maintenance.
• It improves operational efficiency besides
reduction in maintenance efforts. The energy
saving due to regeneration and improved
power factor sizable.

23. Naming of a Locomotive

(Length=1.76m,denoted by W)
Meter gauge(Length=1m,
denoted by Y)
Narrow gauge(Length=2ft
6in,denoted by Z )
Narrow gauge(Length =
2ft,denoted by N)
Types of Tracks
A-ac
C-dc
D-diesel
M-mixed (Both goods and passenger)
AC-Both ac and dc
S-Shunting
