The WAP-5 is an electric locomotive of Indian Railways for operation with 25 kV AC with a frequency of 50 Hz, which is built from the year 1995th After the first eleven locomotives had been imported from Switzerland , construction of the locomotives began in the Chittaranjan Locomotive Works (CLW). The designation of the series consists of W for wide ' Breitspur ', A for alternating current 'alternating current' and P for passenger 'traveler' for passenger locomotives . A 5 follows the hyphen to identify the 5th generation of WAP locomotives.
history
construction
While the WAP-4 was developed for heavy passenger trains , there was no locomotive for the very fast, light passenger trains. In July 1993, received ABB -Landesgesellschaft of Switzerland an order for the supply of locomotives with AC drive in GTO thyristor technology, similar to the locomotives in 2000 the SBB . 22 freight locomotives WAG-9 and 11 passenger locomotives WAP-5 were ordered. A technology transfer contract was also linked to the supply contract, which enabled further production of the locomotives in India.
The locomotive body and bogies of the first eleven locomotives with the numbers 30,000 to 31010 were built in the ABB plant in Dandenong in Australia and provided with the electrical equipment in Switzerland in the ABB traction equipment assembly plant TRAMONT in Zurich Oerlikon . The fully assembled and commissioned locomotives were loaded onto platform trucks and taken over the Hauenstein Pass to Basel for shipping in the Rheinhafen . From there, the locomotives were taken to Rotterdam on inland vessels and loaded onto the general cargo ship of the Shipping Corporation of India (SCI) using a floating crane , which was calling at the port of Calcutta . The first locomotive arrived in July 1995 and was transported by rail to the Ghaziabad depot .
Five years after the first WAP-5 arrived in India, the CLW began manufacturing WAP-5 locomotives. The first locomotive delivered in 2000 with the number 3011 bears the name नवोदित Navodit , German for ' budding ' .
Production started slowly. By 2008 only ten locomotives had been built - typically only one or two new vehicles were built each year. It was not until the 2010s that production numbers rose noticeably.
In contrast to the imported locomotives, the Indian locomotives do not have corrugated , but rather smooth side walls. An exception is the 30013, which received the locomotive body of the 30008, which was damaged by fire before being unloaded in Calcutta.
Newer locomotives have a WBL-85HR pantograph from Schunk above a driver's cab , which is necessary for journeys on routes where the contact line is located at a height of 7.87 m above the upper edge of the rails , so that trains with double-deck container carriers can also run underneath . The abbreviation HR stands for high reach , which indicates the larger work area.
Further innovations are in the conversion of the converter technology to traction converters in IGBT technology, in which the converters for the voltage supply of the 3-phase train busbar are integrated so that the generator cars are no longer required in the trains. Some locomotives are equipped with push-pull control.
In October 2018 the WAP-5 30164 was presented, which was the first locomotive to have aerodynamically optimized front walls and with a gear ratio of 1: 3.11 can reach a top speed of 200 km / h. The locomotive is equipped with surveillance cameras for the drivers and the route. Voice recorders are installed in the driver's cabs .
A software upgrade increased the power of the locomotives to 6000 hp at the end of the 2010s.
For the Tejas Express trains, the construction of WAP-5 locomotives began in 2020 with a one-sided aerodynamically optimized front and a vertical front at the other end. The locomotives have two driver's cabs, but are to be used like power cars at both ends of the train.
commitment
The WAP-5s are Indian Railways' fastest locomotives. In the beginning they were used in front of Rajdhani Express trains, but their trailer load increased over the years, so that they sometimes caused difficulties for the four-axle locomotive, especially in bad weather. The WAP-5 was therefore soon replaced in these services by the six-axle WAP-7 , which are based on the WAG-9 freight train series. The WAP-5 has proven itself against light daytime express trains such as the Gatimaan Express and the Shatabdi Express trains . The Gatimaan Express connects Delhi via Agra and Gwalior with Jhansi . With 12 cars it reaches a speed of 160 km / h and covers the 400 km long distance in four and a half hours.
technology
On the current collector and, arranged on the roof vacuum - the main switch , the energy is supplied to the disposed under the locomotive body transformer supplied. The energy is fed to the two oil-cooled converters via four secondary windings with a nominal voltage of 1270 V, which supply the four traction motors, which are fully sprung in the bogies, with energy. The motors are designed as three-phase asynchronous machines with squirrel cage rotors . They drive a two-stage axle-mounted gearbox via a curved tooth coupling . The Flexifloat bogies are built on a welded cranked frame that offers enough space for the long Flexicoil coil springs of the secondary suspension. The forces of the drive are transmitted to the locomotive body via push-pull rods arranged at the front against the center of the locomotive.
The locomotive's drive train is similar to that of the SBB Re 460 , but, like the first version of the Eurotunnel series 9 , uses a converter with only two voltage levels instead of the converter with three voltage levels in the intermediate circuit. For the first time, a filter winding was added to the transformer , which is located between the traction windings. Apart from a few differences, the technology is identical to that of the WAG-9 and WAP-7.
Named locomotives
The following locomotives have names, although these are only written on the locomotives in Arabic script :
- 30011 नवोदित Navodit , German ' budding ' , first WAP-5 built in the CLW
- 30012 નવ જાગરણ Navjagran , German 'awakening'
- 30013 નવકીર્તિ Navkirti , German 'innovation'
- 30015 विजय उत्कर्ष Vijay Utkarsh , German 'victory of progress'
- 30158 गौरव Gaurav , German for 'proud' , first WAP-5 assigned to the Vadodara depot
