Except for certain connecting routes and dedicated high-speed corridors, they merely operate the passenger equipment on existing tracks owned by freight railways. Local rapid transit systems are usually operated as public utilities by the individual municipalities or transit authorities on their own trackage.
Commuter services may be operated by government agencies or private sector on either their own or other railway owned trackage.
For example, a hp locomotive will have approximately 74, lbs. The maximum tractive force that can be developed at the rail is equal to the weight on drivers multiplied by the adhesion coefficient of friction of the wheels on the rail.
The primary factors, among others, affecting adhesion are rail condition and speed. Adhesion decreases as speed increases.
As all the wheels on most diesel locomotives are driving wheels, the weight of the locomotives must be about four times the tractive force developed. The HHP high horsepower units for main line service weigh about tons each on 6 axles.
The maximum tractive force is therefore approximately 97, lb. As the train speed increases, the tractive effort from the locomotives decreases and the drawbar pull available to move the train also decreases.
Due to the limited strength of drawbars and coupler knuckles, the number of locomotives or motorized axles that can be used in the head end of a train is restricted. Although rated with a minimum strength of , lb.
Grade E knuckles used on some captive services may have an ultimate strength of , lb. To avoid the risk of drawbar failure enroute, it is recommended to limit the number of motorized axles in a locomotive consist to 18 three 6-axle units.
Other resistances due to wind velocity, tunnels or different train marshalling will not be discussed here. Rolling Resistance Rolling Resistance is the sum of the forces that must be overcome by the tractive effort of the locomotive to move a railway vehicle on level tangent track in still air at a constant speed.
These resistive forces include: Rolling friction between wheels and rail that depends mainly on the quality of track. International Students We accept a range of international qualifications, please contact the admissions tutor for more information. Standard English language requirements apply, learn more about international entry requirements.
Depending on your chosen course of study, you may also be interested in one of our foundation pathways, which offer specially structured programmes for international students whose qualifications are not accepted for direct entry to UK universities.
Further details can be found on Birmingham International Academy web pages.
You will benefit greatly from ongoing and substantial investment in new teaching spaces. Labs are kitted out with brand new, hi-tech equipment — supplied by multinational companies like National Instruments — and extensive key software through our partnership agreement with Microsoft. Resources and facilities Your learning is based around dedicated teaching and research facilities, with Electronics Laboratories for teaching and project work.
It will bring together many engineering disciplines into one state-of-the-art building. Collaborative Teaching Laboratory The Collaborative Teaching Laboratory CTL is a hub for science and engineering teaching, with multi-functional labs suitable for subject-specific and cross-disciplinary teaching and team working. How you will learn We are a small department within a large engineering school — so you get the best of both worlds.
You will be taught from a combination of large-scale lecture tuition, small-group teaching six students or fewer , and lab and other practical classes.

Practical sessions typically last two to three hours, although more advanced experiments and activities may span over several sessions.
All of our undergraduate programmes feature a significant level of project working in each year of study, with individual and group projects designed to prepare our graduates for teamworking, problem solving and project management.
Feedback is an essential part of learning and we use a wide range of methods, such as written feedback on your assessments, class feedback sessions and discussions with your tutor.Shear connectors may be either steel channels or headed studs welded to the top flange of the steel and embedded in the concrete deck.
Grade E knuckles used on some captive services may have an ultimate strength of , lb. It starts with minor deflections and may progress to a fully visible surface heave, where subgrade material is pushed above the elevation of the rail and ties.
