TRURO IN 1971
Details from Roy Hart
Really fascinating information
The layout and signalling at Truro altered hardly at all from its installation in 1900 for seventy years.
The two Truro boxes-East and West, both opened with the new station (built by Sir Arthur Carkeek and Co of Redruth) and they controlled an extensive layout:
From South to North, the lines were:
Falmouth Bay (signalled for departures only)
Branch Platform (signalled as an up through line, but used by terminating Falmouth and Perranporth trains and Penzance locals.
Up Main (the outer face of the island platform)
In addition, there were the following through lines, signalled by ‘Permissive Block’:
Through carriage line
Through down goods
Through up goods
Permissive block entailed block instruments and bells, but allowed more than one engine or train in the section. The signalman had a ‘counter’ on his instrument to remind him. Thus there were no less than 6 through lines between Truro East and West, all with block instruments and a series of block bells, all of different tones, so that signallers could tell them apart.
The 1971 plan was to concentrate all of the work (together with Penwithers Junction) at Truro East box.
Phase 1 (May 1971):
-Through Carriage and up and down goods out of use, replaced by simple ‘yard’ working.
-Branch platform becomes up main.
-Up Main terminated at buffers East end, for arriving Falmouth trains (temporary arrangement).
-Engine shed and Carriage sidings removed.
Phase 2 (November 1971):
East box temporarily closed for installation of new lever frame (old frame 45 levers, new frame 51)
West box controls all traffic.
Penwithers closed and junction simplified, enabling Falmouth trains to run into Falmouth bay (No 1)
Up bay (No 4) out of use for passenger trains. Remains as siding.
At the end of phase 2, West box was closed and the new ‘Truro’ box controlled the entire layout. At that time, the remaining yard could still be accessed from the East end. This junction was removed in the 1980s.
The remaining points at West box end were (are) operated by motor.
The new frame at East box came from the redundant box at Bristol East Depot, closed under the Bristol resignalling scheme. The frame was of 90 levers. One section of it went to Hungerford, near Reading, where the box had been demolished by a derailed freight train, the remainder to Truro.
Penryn box closed under the same scheme and the entire Falmouth branch worked by ‘No signalman token’. The instrument was in a cupboard by the bay line buffers. The token was released electrically by the signalman .
Many thanks to you Roy for this detailed report on the phased changes at Truro Yard in in the local area.
14th October 1989. 47811 paases with the 0905 Brighton to Plymouth.
19th October 2017. The Network Rail HST passes with the 0456 1Q23 Old Oak Common - Honiton - Exeter - Salisbury, whilst in the turnback siding is GWR Class 150 150121 which will run to St James' Park to form the 0920 service to Cardiff.
Looks like it was a dull day in 1989. The photo of the NMT was taken from my video footage on yet a similar dismal day.
Dave Many thanks David.
