LZ, I went to Penrith,via Windermere and Keswick, on a Friday afternoon a couple of months back. 5hrs, including stopping for sit down hot meal. Can’t do a train in that time.
That’s about as bad as it gets unless roads get closed. Remember rail lines get severely disrupted as well.
I type this on a delayed Chiltern train, running behind due to ongoing issues at Ealing (nought to do with Chiltern lines, which go nowhere near Ealing)
So not 3.5 hours then TB
Obviously you CAN do long distances, say from South to North, in all kinds of times, all dependant on LUCK mainly, and I'm speaking as a million mile business driver who travelled across the country back in the 1970's-90's. Even if I set off at 0300 hours in the morning, which I did on many occasions, it would not dictate what time I actually arrived say in the North East or North West; it was dependant on how many accidents, road works, or,very importantly, time of the year.
I must be honest to admit my runs to the Lakes have always been in August, so the type of traffic i.e.the amount of Pikeys with caravans, that sometimes were on their sides blocking all lanes (that happened so many times going down to the South West I lost count) made a big difference. So the times I quoted were the worst possible I know, but that is what happened at that point in time. As I said to do that run in 3.5 hours is really pushing it and totally relies on luck. No matter how fast you drive, as I well know, if you face miles of near stationery, or even stationery traffic, as has happened so many times to me in the past making my days very long, you cannot drive at anything but 0-10 miles per hour. That resulted in journeys like one I did in 1990 from the North East to Bristol taking 11 hours, that I could normally do then in 3-4 hours.
As for the trains we are all talking about the current situation; no, out of choice I would not use the railways for any long distance journey going away from London being a true female motorhead who loves my car and driving. However for 4 years I used to commute to my business in London from both the Midlands (yes, via Chiltern Railways which I found to be excellent usually) and the South East as it was far easier than facing London traffic then finding convenient, and not too expensive parking. I still do commute by train to London from my home town which means, usually I arrive in the big city in just over 1 hour by High Speed train. Try driving to London from here during a normal day in that time, especially during the peak periods! You are doing well to do it in 2 hours. Some journeys have taken me 3 hours.
But that is in 2018. Once we (well, I do not think me!!) get to 2050/75 the railways will be very fast across the country, with, I predict, a means of automatic transport taking you from your front door to the train station, and being the same at the other end. As said it will be very fast, very efficient (without the failings of, like this TB, the "Victorian" system) and relatively cheap. That is cheaper than maintaining and fueling the motor cars of today, with in 2050 the often mentioned "self driving" cars doing the short journeys.
Wishful thinking? Well maybe!! But just think how man advanced transport from 1900 to 1975 (no flying to Concorde and landing on the Moon) and with the pace of technological advancement increasing what was previously achieved in 75 years COULD be achieved in just 40 years if man/women has the will, finance, and determination to do it
