Apologies if this has been covered before, but I can't find any previous references to this specific question.
The max line speed, on the fast lines, between Clapham Junction and East Croydon seems to be, from my observation of lineside speed limit signs, 70mph. Which is great. I was on a class 377 EMU at the time.
My mate had an 'app' on his mobile phone, which once we got going, indicated a near-constant 70mph speed shortly after Clapham, only slowing down just before Selhurst, presumably to navigate the complex junction located on the approach to East Croydon.
My question is: why is it that this run does not achieve a maximum speed more than that? Given there is a relatively sharp curve in the line between Balham and Streatham Common; could that be the reason?
Or could it simply be due to the relatively short distances between the stops, even though the train in question, given enough distance, is capable of 100mph, it would not be efficient to do so.
This isn't a moan; I'm just curious.
Thanks.
