The weary stoicism of the British train traveller is legendary. But basic good manners and respect for your fellow passengers will go some way towards making even the most crowded train journeys more tolerable.
Golden Rules for Train Travellers
Wait for other passengers to exit before boarding the train: never jostle past people who are trying to get off.
Always give up your seat to someone who is elderly, disabled or obviously pregnant. Mothers with small children in tow should also be given priority. If necessary, help people to put their luggage in the overhead racks.
Some train carriages are very quiet, packed with commuters reading newspapers or working on their laptops, so be aware that loud mobile phone conversations are very disturbing. If you are going to listen to music on your MP3 player, ensure that you have sound-proof headphones.
Be aware that eating greasy, smelly food (such as burgers) may well nauseate your fellow passengers, and is a major cause of litter.
Keep personal grooming private: no tweezing, plucking, manicuring etc. on public transport.
Ask people if it's acceptable to open windows. Open doors for people if they are awkward or require strength. When going to and from the buffet avoid bumping into people. If seated do not impinge on the aisle space.
If the carriage is crowded don't take up an additional seat with your excess baggage: you haven't paid for two seats. No one should ever have to ask you to move your baggage. Don't sprawl in your seat, or put feet on the seat opposite.
Help people off the train with heavy baggage, mothers with pushchairs and elderly passengers who find the step down difficult.
Put discarded newspapers, coffee cups and so on into the bin - no one will want to sit surrounded by your detritus.
