Recently got chance to travel from London to Oxford in local trains which was just like semi fast Mumbai as had limited stop as after departure from London marylebone it had not halt for 30 mins but after that it halted every station.As In UK majority of it's rail network is not electrified since our train was hybrid as can run both electric and diesel as till half way it run on electric traction then it switched to diesel as oxford Cambridge section still not electrified as only major cities section only electrified.I was surprise as our train ran at mps of 130.It was really good experience to experience intercity fast local trains.
