The WAP-3 was the upgraded variant of the WAP-1 with a higher top speed of 140 km/h. All units of this class were WAP-1 units already in service. The first locomotive converted was a WAP-1 22005 Jawahar. Subsequently 8 more WAP-1 were converted, but since the class were not a great success and had performance issues, these were converted back ...
The WAP-4 class was developed after its predecessor, the WAP-1, was found inadequate to haul the longer, heavier express trains (24-26 coaches) that were becoming the mainstay of the Indian Railways network. IR/RDSO had realized that the reason for the WAP-1’s performance problems were the low-powered 770 hp Alstom TAO 659 traction motors.
The history of the WAP-3 begins in the early 1980s with the WAP-1 class. The WAP-1 was the first attempt to create a dedicated high-speed electric passenger locomotive. [ 1 ] They were first used on the Howrah Rajdhani Express , [ 2 ] but Indian Railways was not satisfied with the performance of the WAP-1, as they could haul around 19 coaches ...
Tết Đoan Ngũ, Tết Trùng Nhĩ or Tết Nửa Năm (Nửa Năm: a half of a year) is a festival celebrated at noon on the fifth day of the fifth lunar month. [1] This day is the day around the time when the tail of the Great Bear points directly to the south, that is, around the time of the summer solstice.
This class provided the basic design for a number of other locomotives like WCAM-1, WAG-5A, WCG-2, and some WAP-1 models. However, with the advent of new 3-phase locomotives like WAP-5 and WAP-7, the WAM-4 locomotives were relegated to hauling smaller passenger trains and most of the units have been scrapped. A few units are in service ...
For shunting up to 15 km/h (9.3 mph), it can haul 7,500 tonnes (7,400 long tons; 8,300 short tons) on grades of 1 in 1000 (0.1%) or less. The atmosphere may be humid and salty. Regenerative braking will provide braking force of no less than 260 kN (58,000 lb f ) at 10–62 km/h (6.2–38.5 mph) and closer to 260 kN (58,000 lb f ) at higher speeds.
The Indian locomotive class WAG-1 was a class of 25 kV AC electric locomotives that was imported from Europe in the 1960s for Indian Railways. The model name stands for broad gauge (W), AC Current (A), Goods traffic (G) locomotive, 1st generation (1). A total of 112 WAG-1 were built by The European Group 50 Hz Group/European Group/50 Cycles ...
