चलती है (ग्वालियर-भोपाल वाया गुना बीना ICE) उड़ती है धूल जलते है दुश्मन खिलते है फूल - Adi Singh

Built by CLW to RDSO specifications. First in the dedicated electric passenger loco series. Production began in 1980 and the locos were at first used solely for the Howrah-Delhi Rajdhani. A single WAP-1 (#22001) was all that was needed to haul the 18-coach Rajdhani at a max. speed of 120 km/h. and an average speed of around 82km/h. Continuous power 3760hp; starting TE 22.2t, continuous TE 13.8t. Loco weight is 112.8t.
The original WAP-1 locos were modified and regeared versions of the WAM-4, originally classified WAM-4R. Rated max. speed is 130km/h (some documents suggest 140km/h). Some (5?) with Flexicoil Mark II bogies were classified WAP-1 FM II and later WAP-3. Two WAP-1 units were also converted to WAP-6. [10/02] One of them,...

#22212, the first prototype WAP-6, was then converted to a WAP-4 and was based at Jhansi (now [8/03] at Mughalsarai).
Many remaining WAP-1's are being converted to WAP-4's by a complete retrofit including new traction motors, new transformers, etc. These upgrades do not result in the 'R' suffix in the road number that is typical for rebuilt locos. Ghaziabad shed locos are currently [1/05] the only ones not scheduled for such upgrades and are expected to remain as 'pure' WAP-1 units. The WAP-1E has only air brakes. Earlier WAP-1's had loco air brakes and vacuum train brakes but were retrofitted for dual train brakes. Motors are grouped in 2S-3P combination and weak field operation is available. Elgi compressors, Northey exhausters, S F India blowers. The locos were originally not designed for MU operation but were later modified to allow MU'ing.
