I've been thinking for some time about the best way to respond to this.
Those of you who have been around here for a while probably know this, but for the benefit of those new folk, my work history for the last many years has been on and around major railways and trains, both here in England and the US, and before that on short lines and preserved railways here and in the US.
I have been over, under, and in many different types and vintages of train and train carriages. I have, unfortunately, had many run-ins with drunk people, sports fans, and a few people who for various reasons wound up badly maimed or dead on and under trains.
I have also known - never counted them - probably millions over the years - of passengers and staff who safely ride trains every day and the worse they get is when their neighbour across the table from them accidentally kicks their shin and they get a bruise.
Trains are extremely safe, an extremely comfortable way of taking lots of people a long way in complete safety. 1,700,000,000 - (that's 1.7 billion) journeys were made on trains in the UK in 2016-17. There were 66 billion passenger kilometres. The were 15 passenger fatalities during that time, 7 of which were in one very unfortunate tram accident in Croydon, and 1 workforce fatality in that time. So with regard to train passengers that is something like 1 fatality in every 212.5 million journeys. Pretty safe, I'd say.
But as safe as that is, people have to remember how big and dangerous trains are if not respected and warnings heeded.
I think a reminder to take the signs seriously every once in a while is good. Remain behind the yellow line on a platform is a good one - they weren't pained there by aspiring Rembrandts. You would not expect the strength of wind kicked up by a 125 mph train passing a metre away from you as it passes through a station. That's why we tell you.
And the other warnings like keep your head in (still very valid more than the UK in continental Europe), don't put your fingers in the window hopper, don't throw bottles out the window, wait for the train to stop before opening the door, don't get off the train on the wrong side, don't flush the cat down the toilet, don't step on the Third Rail (or any rail for that matter) - these are all (yes all) recent or current signs on the trains. They are there for a reason.
An ounce of prevention is worth a pound of cure.
As I say, I speak from personal experience. A good friend of mine was killed many years ago when switching freight trains in a yard in California. He had worked on the railroad for over 20 years. He looked the wrong way once and was gone.
Read the signs, obey the signs.
And I will say that in the vast majority of cases, not all, and not my friend, alcohol and now drugs plays a great role. You wouldn't believe some of the things I have seen when drunks and trains are near each other.
I've never seen anybody open a moving train window to be sick. It is usually the lap of their friend or nearby passenger or the floor or doorway if they don't decide to use a toilet.
Bottom line - come to England. Ride the trains. Read the warning signs. Be safe.
