TELEVISION viewers throughout South-west and Central Scotland were

faced with blank screens for three and a half hours yesterday after an

electricity pylon collapsed near Newhouse, Lanarkshire, putting BBC and

Scottish Television's main transmitters at Kirk O' Shotts and Blackhill

out of action.

Screens blacked out at 3.15 and normal service was resumed shortly

after 6.50pm. Although BBC1, BBC2, and Channel 4 programmes resumed

immediately, Scottish Television's Scotland Today was plagued with

further technical difficulties.

The breakdown affected an estimated three million viewers from

Ayrshire and the South-west to the Lothians. Switchboards of both BBC

andScottish Television in Glasgow were swamped by hundreds of calls

seeking an explanation for the lack of pictures.

It was the longest recorded interruption of television programmes in

Scotland, but viewers in parts of Edinburgh and East Lothian with sets

tuned to the Burntisland transmitter in Fife were able to receive BBC1

and BBC2.

The power failure was caused by the collapse of an electricity pylon

in an area of open cast mining between Old Edinburgh Road, Newhouse, and

Newarthill.

It also left 20,000 householders in North Lanarkshire without

electricity. Main areas affected included Newhouse, Cleland, Shotts,

Harthill, and parts of Motherwell and Wishaw.

The collapse is thought to have been caused by subsidence resulting

from the recent prolonged spell of heavy rain.

The spot where the pylon came down was close to where some of the 20

employees of the mining firm were working.

Mr Brian Smith, 45, a director of Cochrane Mining Company, said: ''No

men were in any danger. We are still trying to establish what caused

it.''
