How is GTKM calculated in railway?
eTransportation of 1 tonne goods for 1 km. GTKM stands for Gross Tonne Kilometers i.e It is total weight of locomotives and vehicles. Answer: NTKM-Transportation of 1 tonne goods for 1 kilometer.
What is the maximum speed of WAP 7 locomotive?
With a maximum speed rating of 180 km/h, the WAP-7 boasts of the most phenomenal acceleration figures while hauling mail/express trains. The WAP-7 can also haul loads of 24-26 passenger coaches at a speed of 110 plus km per hour.
How do you calculate tractive effort?
S = distance between the axle and the nose. T = Tractive effort at the rails. The force at the gear teeth = TD/d and its direction is downwards on the gear wheel and its reaction on the pinion of the motor is upwards. As a result of this, motor nose exerts an upward force F on the bogie truck.
What does WAP mean in Railway?
The Indian locomotive class WAP-1 is a class of 25 kV AC electric locomotives that was developed in 1980 by Chittaranjan Locomotive Works for Indian Railways. The model name stands for broad gauge (W), AC Current (A), Passenger traffic (P) engine, 1st generation (1). They entered service in late 1981.
What is SFC in locomotive?
Specific Fuel Consumption of an engine may be defined as the amount of fuel consumed per unit work done. i.e. SFC = Amount of Fuel consumed (in Kg/ gms/ lbs/….. )/ Amount of work done.
How is SFC fuel consumption calculated?
In traditional units, it measures fuel consumption in pounds per hour divided by the brake horsepower, lb/(hp⋅h); in SI units, this corresponds to the inverse of the units of specific energy, kg/J = s2/m2.
Does WAP-7 have AC?
The Indian locomotive class WAP-7 is a class of 25 kV AC electric locomotives that was developed in 1999 by Chittaranjan Locomotive Works (CLW) for Indian Railways.
What is tractive effort in EV?
Definition: Tractive effort is defined as the force at the rims or the outer edges of the driving wheels of moving trains. In other words, it is the sum of the tractive force and rolling effort on the road surface.
What is the formula of SFC?
TSFC or SFC for thrust engines (e.g. turbojets, turbofans, ramjets, rocket engines, etc.) is the mass of fuel needed to provide the net thrust for a given period e.g. lb/(h·lbf) (pounds of fuel per hour-pound of thrust) or g/(s·kN) (grams of fuel per second-kilonewton).
What is the full form of WAP 4?
The Indian locomotive class WAP-4 is a class of 25 kV AC electric locomotives that was developed in 1993 by Chittaranjan Locomotive Works for Indian Railways. The model name stands for broad gauge (W), AC Current (A), Passenger traffic (P) engine, 4th generation (4). They entered service in late 1994.
What is the meaning of WAG-9?
The Indian locomotive class WAG-9 is a class of 25 kV AC electric locomotives that was developed in 1995 by ABB Group (ABB) for Indian Railways. The model name stands for broad gauge (W), AC Current (A), Goods traffic (G), 9th generation (9) locomotive. They entered service in 1996.
What is the general formula for acceleration?
General Formula of Acceleration We already know that velocity is a speed with direction; therefore, it is a vector quantity. The acceleration ‘a’ is given as: a = Change in velocity/Time Taken
When did the CLW WAG-9 traction motor come out?
Of these, the first six were fully assembled and rest were in kit form. CLW started producing of WAG-9 traction motors on 1 November 1999. The units built by ABB have pantographs with two end horns while the CLW built units have pantographs with single end horns which are common in India.
What is the power of a WAG-9 with IGBT?
With IGBT, even if one traction motor failed, other traction motors can function with a total output of 5500 hp. Newer WAG-9 units have “CLW Glorious 60 years” marked on their sides. Some WAG-9 (x)s are fitted with a solid cowcatcher while others are fitted with grilled cowcatchers.
