WCAM (W -broad gauge ; CA -Both DC and AC ; M -for both goods and passenger service) is the dual-power AC/DC series locomotive used by Indian Railways. These locomotives could run under both DC traction and AC traction. All the WCAM locos except the WCAM 1 (made by CLW) were made by BHEL. They had 750 V DC traction motors, using resistance banks in DC mode and a variable ratio auto-transformer with rectifier units in AC mode, for power control.

The WCAM class locomotives are in service only in the Mumbai region. The dual-voltage WCAM series locomotives hauled intercity trains out of Mumbai DC suburban region which was on a 1500 V DC overhead system, as opposed to remaining India which have 25000 V AC overhead.

Mumbai suburban region has completely switched over to 25000 V AC by 2016 and so the WCAM locomotives are no longer required. Now pure AC locomotives run in this region. However, WCAM(2/3/G1) locomotives continue to be used in AC traction.

Types

There are four types of Locomotives under WCAM class:

Mixed type locomotives

• WCAM 1
• WCAM 2
• WCAM 3

Goods locomotives

• WCAG 1
