This was of course what lay behind the accident at Elsenham, on the Bishops Stortford-Cambridge line, where there was only a level crossing, all the village houses are on the Cambridge-bound side but all ticketing facilities were withdrawn there for economy, passengers travelling to Cambridge then had to cross the line twice, to the London-bound side to get a ticket, and then back to get their train, across a busy 2-track route. And also cross the road through traffic.
All (partly) sorted out after the event of course - but too late.
