Protestors against a new platform for the historic Helston Railway will be celebrating after it was refused planning permission by Cornwall Council, although the railway's supporters have vowed to appeal.

The plans for a new platform at Prospidnick, in Sithney Parish, along with an extension to the railway track, sidings associated buildings and a car park, were turned down by the council's west sub area planning committee on Monday afternoon.

The application was rejected due to overlooking and noise to nearby residential properties, in particular Gansey House.

A group of campaigners raised 223 signatures on a petition and recently marched through Sithney to protest the plans, and organiser Clive Perrin said he was happy with the result.

He said: "We won the day. The signatures were very fruitful in turning it down."

He described the campaign as sticking up for the neighbours of the railway and said "old diesel engines are really not what you want going by the back of your garden."

Sithney parish councillor Clive added: "I was pleased we won, on the basis that when you have a parish council supporting its local residents you feel happy that... you are returning their lifestyle and there will be no interference with their everyday living."

Richard Barnes of Helston Railway said: "The volunteers who have put time into the railway are a bit dismayed.

"We are going straight to an appeal."
