The most incompetent approach to this was Elsenham, on the Liverpool Street to Cambridge line, where in 2005 two girls were killed crossing the line

Platforms separated by a level crossing, used to be ticket offices on both platforms, but in an economy the one on the Cambridge-bound platform was closed, and no TVM was provided. The village is wholly on the Cambridge side of the line, meaning passengers headed north now had to cross the line on the level twice, once to get a ticket and then again to get their train. The main road was gated but the foot crossing was not secured. This was all completely ignored by the Risk Assessment of closing the northbound ticket office, especially the likelihood of there being multiple trains closing the crossing for an extended period. The only action by the TOC had been putting up notices warning boldly of penalties for anyone boarding without a ticket.
Notably after the accident a TVM was provided on the northbound side, followed by a footbridge - which of course now served little purpose. Network Rail were fined £1m for this but the real culprit was surely the TOC manager who decided to close the ticket office and not provide a TVM to save a few bob. It was the second comparable fatality that had happened there.
