hicksy3 Posted October 2, 2015 Share Posted October 2, 2015 Electric trains just pull/push the train along. Diesel trains are far more complex. The diesel motor doesn't push/pull the train. It either powers a generator to power electric motors to push/pull the train along. Or drives a hydraulic transmission to push/pull the train along. Complexity causes loss of efficiency and higher maintenance costs. Rail is different to road in terms of electric/internal combustion being optimum. The electricity gets delivered 'fresh' to the train by OLE or third/fourth rail. Electric trains don't need batteries like electric cars, so their economic, environmental and social benefit (DEFRA reckon poor air quality cost the UK £9-19Bn last year, diesel trains played their part) is clear.

Happ Hazzard Posted October 2, 2015 Share Posted October 2, 2015 Sheffield needs a monorail if it wants to come into the 21st century. A monorail and some skyscrapers of at least 100 storeys. Link to comment Share on other sites More sharing options...

mattleonard Posted October 2, 2015 Share Posted October 2, 2015 Sheffield needs to become the city of the future instead of being stuck in the 19th century. I guess that you could class not having a monorail as accurately reflecting the 19th century; but it generally reflects the 20th century and most places in the 21st century so far - and I suspect (based on predictions of what the year 2000 was apparently going to be like) may well reflect the 22nd century too. How about Sheffield embraces its current strengths and seeks to evolve those, rather than focus on theme park gimmicks, or building towers (which experience shows often turn into bitter rows about cheap cladding)?

You need to stand as a councillor, this city needs someone with your special vision. Link to comment Share on other sites More sharing options...

Er no... There are both diesel and electrical multiple units on the UK rails today, as well as diesel and electric loco hauled units. Efficiency is not necessarily any higher in an electric train either - you still have to generate the power and a diesel prime mover can be more efficient than a power station in generation...
