sorry for wrong question.

will railway line electrification reduce the running time?

This is a proper question in the "rail" section of T!A. Where is one's proper reply?

The question was whether "electric" powered trains would reduce "running time" between at least two points. DTT SCW, whom I used to refer to as "Da ACE' is correct Torque is what accelerates. On board power supply eclipses that which power is distributed over long distances, even with relays, pretty quickly.

Running time is an average between two points. Assuming the points are not in close proximity, differences in acceleration is negligible. Electricity is merely an alternate power source. The train will run cleaner, but running time is running time.

No, electric powered engines will not reduce running time.

No slow them down.
he UK East coast electrification was supposed to reduce running times by allowing 140 MPH but it never happened, still stuck at 125 and diesel HST and electrics run the same schedules.
The expensively electrified West Coast main line has a 110 mph limit north of preston whilst the un electrified GWR main line rund 125 mph with diesels.
Reason every diesel can produce maximum power when ever required, however electrics are restricted by the power from the electricity sub stations, and the number of other trains drawing current at the same time. This is why TGVs can do 150 mph in Escargot land and only 75 in Kent.

The fastest accelerting trains in UK were class 91 electrics on test from Kings Cross which used spare HST power cars with 2250 HP Diesel engines as driving trailers, someone found diesel and electric could be operated together so 7250 HP gave stuning accelertion sadly proper DVTs were later provided.

Electrification, merely allows the pollution from Coal or Nuclear power to be seperated from the train.
In terms of whole life energy consumption, including infrastructure electrification is inferior to diesel, Only in pollution at the train is electrification environmentally friendly.
You wouldnt want a diesel underground train would you.

Not at all. The old train timetable from New York to Wash DC show they ran faster when they were steam. The time mostly depen das on the rails thant often require slower speeds.

An electric train is going 120 mph due South, goes into a gradual turn and is now doing 90 mph due East, goes into another turn and is now going 140 mph due North, goes into another turn and is now going 150 mph due West, as the train continues West which way does the smoke go?

Depends on the equipment chosen, however the fastest trains are electric

This makes no since to me If you are referring to locomotives they do use electric motor's that is powered by a diesel turning a generator

Not really...about all it will do is take a few seconds off acceleration after each stop..

please try to give me a proper question. the train runs with electric motor
