An electrified rail line between King's Lynn and Cambridge has been hailed as one of the key drivers of the region's economy by the author of a new book which tells its story.

There was talk of closing the struggling King's Lynn to Cambridge line in the mid-1980s.

Sections had been reduced to single track, while with no overhead power, stations north of Cambridge could not be served by the latest electric commuter trains.

"By the early 80s, the decline north of Ely was apparent," said Mr Beckett.

"The singling of major parts of the line had led to a feeling that it was on the way out."

"There had been surveys showing the upswing of population that was coming at the time and we found the majority were coming from the south east," he said.

"What was driving it was house prices, which were a jolly sight cheaper here."

While people were moving to the area to improve their lifestyles, they needed to be able to get to their jobs in Cambridge or even London.

"Driving down the journey times became a key driver in the improvement of the local economy," said Mr Beckett.

The government gave the go-ahead for the £40m upgrade in 1989 and the first electric trains were running by 1992.

But there are fears future improvements have been shunted into a siding because of rising costs.
