Train operators EWS want to put an eight - not four - wheeled wagon in the middle of the train to try to break the pattern of tremors.

It is hoped this will lessen vibrations described by residents living near the line as 'an earthquake.'

"Everybody at a meeting on Friday certainly believed it was worth a try and agreed to take part in this experiment," said a Macclesfield Borough Council spokesman.

The four-axled truck - known as a bogey - will be linked in the middle of freight trains that haul limestone from Buxton to Northwich-based Brunner Mond.

But now EWS have to find a truck to use and check it will be safe.

"We haven't gots lots of spare wagons because most of them are in use," said a company spokesman yesterday (Tuesday).

When the bogey is finally in place all local authorities along the line affected by vibrations, will test tremors with equipment used to measure earthquakes. Readings will then be used to see if vibrations have lessened.

Yesterday EWS said all parties at Friday's meeting - including the council, Railtrack and Brunner Mond - had agreed that tremors weren't causing damage to homes near the line.

But Clr Jan Verney and Clr Sue Kipling, of Plumley, also affected, denied this and demanded Railtrack take responsibility for the problem.

"It was almost impossible to prove structural damage," said Clr Verney.

"We have graphs and videos taken from a house in Knutsford and they show considerable vibrations."
