Hi all,
I'm told by industry sources that there is constant monitoring of 2 large (their words, not mine) slips in the area of Unstone just south of Dronfield close to 149mp. Estimates are that 75,000 tonnes of spoil are moving - this is the material that was used to stabilise the same site in 1970, where, in 1969 Broomhouse (not Broomhill) Tunnel existed before it was opened out into a cutting.
Preparatory work is going ahead sending machinery and staff to site to try and halt the slides but it is expected that that one of them at least is likely to slip further before work can be started and cause the line to be blocked. Estimate for the slip to move is 7 days but this is likely to be shorter as heavy rain is forecast for this weekend.
There is an estimate of 7 - 14 days before both slips can be remedied. Some very minor track movement has already been noted.
If both lines are blocked passenger and freight diversions will be via the Old Road (Beighton and Nunnery). Northern services between Leeds and Nottingham will terminate at Sheffield with passengers forwarded on, presumably, EMT Norwich services with an additional stop at Langley Mill. Cross-Country look likely to run one train via Sheffield (reverse) per hour with the other running direct via the old road from Masborough to Tapton
If one line remains open, traffic will run over it in the direction in which it is open, with diversions via the Old Road for trains in the blocked direction.
Both lines remain open at the moment but the situation is under constant monitoring.
