Just North of Milton No 1 Crossing - below,
numerous strange construction vehicles are visible from the
train. This is the start of duct drilling below the track for
undergrounded high voltage cables from Tom Nan Clach Windfarm some distance further North
on Cawdor Estate land.
The Developer agreed a wayleave with Strathspey Railway Co. starting in early
2017 and since then there have been many documents to review and approve
including pre-start rail head surveys.Track walkers will have noted survey marks on the sleepers
in the vicinity used by an independent surveyor in monitoring the rail head
level to record if any settlement occurs.
First of four ducts to be drilled (above) from just
outside our fence which head steeply down so as to be approximately 6 metres below
the track. The ducts then carry on deeper and run below the the River Spey to
emerge north of their destination at the Sub Station on the Nethybridge Road.
The Cairngorm National Park Authority (CNPA) dictated these cables had to go underground.We are advised that existing overhead HV wires in the vicinity (just visible top right)
are likely to be undergrounded to satisfy CNPA requirements. We look forward to
more income but not to the paper trail that will be part of it!
Of a similar nature to this work, a considerable length of pipe is being laid in the "four foot" (between the running rails) for testing purposes, necessitating the removal of one of the wooden planks of a number of level crossings, above today's squad (left to right - Martin, Roddy, Mike & Roger) admire their handy work at Croftnahaven No 1.
And the way the pipe is got there! - notice no tail lamp on "Shark" Brake Van as train not quite complete!
A bit further up the line a large "Christmas tree" had been blown over in recent gales and we were detailed to cut it back further, to clear the cess (it had previously completely blocked the line)
After considerable huffing and puffing - job done.
Thanks to all that assisted today and Mike for most of the info and I would like to wish everyone a Merry Christmas and look forward to keeping you updated in 2019.
And from our Signalling & Telecoms (S&T) colleagues -
Friday the 14th December saw the installation of a new signal in Aviemore Station which will manage the interface between the new Network Rail Signalling controlled from Inverness and Strathspey Railway managed Infrastructure in Platform 3.
The excavation work was carried out by Andrew Muirhead (above) and signal post preparation and painting was carried out by David Dow (below in High Viz)
The S&T installation team were ably assisted by Nathan Lightowler and the Telehandler machine from Aviemore Shed.
And from our Signalling & Telecoms (S&T) colleagues -
To accommodate the correct signal arm bracketry and also through routes for cables entering the post and running underground in ductwork, the signal as repurposed at Aviemore (South), required accurate marking and drilling of the original signal post (measure 3 times and do it once – although drill bits were easily blunted by the hard steel post). The signal features volt-free electrical contacts as tellback to NR systems.
Stephen burns the midnight oil (below) early last week.
