How is the adhesion limit of a locomotive calculated?
From A, B and C a coefficient CK is computed, and the adhesion force limit is then calculated by multiplication of CK by the car mass and the acceleration of gravity (9.81), as better explained later. The adhesion limit is only considered in the adhesion model of locomotives. The adhesion model is calculated in two possible ways.
When do new shunt signals come out for Stepford County Railway?
In February 2020, with the release of Version 1.4.1, new shunt signals were introduced at Faymere Green TMD. 2 white lights mean proceed and 2 red mean stop. Although SCR uses an advanced signalling system, collisions still occur, mostly at the City Hospital Triangle, near the station of City Hospital.
How are diesel locomotives bad for the environment?
Although diesel locomotives generally emit less sulphur dioxide, a major pollutant to the environment, and greenhouse gases than steam locomotives, they are not completely clean in that respect. Furthermore, like other diesel powered vehicles, they emit nitrogen oxides and fine particles , which are a risk to public health.
How long have you been involved with railway traction and rolling stock?
We have been involved with railway traction and rolling stock for many years – our Managing Partner was an engineering apprentice at the Works Training School in Swindon – and over this time we have accumulated a large amount of traction and rolling stock training manuals.
How are shunts used in the rail industry?
In the rail industry, a shunt merely consists of C-clamps and low resistance wire. This is made in order to simulate the conditions of the track while a train is passing over it whe the axles create a very low resistance connection across the tracks. This enables various signal protocols to take place.
What do you need to know about a shunt?
A rail shunt is defined as a low-resistance wire apparatus, which, when clamped to the parallel tracks, will create a short-circuit between them. This is done to mimic the conditions present when a locomotive or rail car is shorting a section of powered rail. In order to be an “effective” shunt, the total resistance between the rails
Who is required to be a Ground Shunt crew member?
6 Movement (shunting) of rail vehicles is a collaborative effort between the locomotive driver and the ground shunt crew. For the purposes of this unit standard, a qualified ground shunt crew member must be used during assessment. 7 Definitions
What causes a clunking noise on the driveline?
Cause: Bad wheel bearings Noise: Driveline squeaking or grinding at any speed Cause:Worn or damaged U-joints Noise: Clunking when depressing the throttle pedal (takeoff) Cause:Worn U-joints; worn spider gears; worn axle splines; excessive gear backlash; loose yoke splines; worn slip yoke splines Noise:Clunk immediately after taking off from a stop
