Interlockings

2014-07-16T23:04:59Z

Daniel Evans: Remote interlockings link

The interlockings controlled by Swindon Panel have a standard circuitry design known as BR(WR) E10k, derived from the reference number of the series of drawings describing this design (E10000 series). It is a freewired interlocking design (Western Region never used geographical interlockings). The term 'freewired' means that all of the interlocking is bespoke to its particular location, consisting of individual relays wired together to suit that particular application. By contrast, a geographical interlocking consists of pre-wired generic packs of relays which are combined together like building blocks to build up the interlocking. Geographical interlockings are quicker to install and require less on-site testing but as not all of the available functions in each relay pack may be required there can be considerable redundancy. The wasted expenditure of this redundancy and the higher initial cost of pre-packaged units has to be balanced against the savings in installation and testing costs. Western Region decided that, in their opinion, freewired interlockings provided better value for money.

The first E10k interlocking was installed at West Ealing in 1955. The panel at West Ealing was supplied by MV-GRS to their standard NX Turn-Push design and the E10k interlocking system was influenced by MV-GRS interlocking practice.

The table below shows the interlockings in the Swindon Panel area:

The Uffington interlocking was commissioned before Swindon Panel came into existence as it was originally controlled by Uffington signal box. It migrated to control by Swindon Panel on 3 March 1968.

The Swindon interlocking is located at the signal box with the panel and is controlled directly. All the other interlockings are sited at their geographical locations, remote from Swindon Panel, and are controlled through remote control systems.

==Swindon MAS Stage 3 - Thingley Junction to Bathampton and Bradford Junction==

The third stage of the MAS scheme concerns the [[Chippenham]] to Bathampton and Bradford Junction area, and is described in notice S.2503, planned to be implemented Saturday 25th February to Sunday 26th February 1967 on the main lines and from Sunday 26th February to Monday 27th February on the branch lines.

[[Corsham]] Signal box was taken out of use and its equipment recovered.

[[Melksham]] Signal Box was already out of use since 1630 on Friday 24th February under notice [[S.2502]].

Continuous Track Circuiting (CTC) was installed between [[Thingley]] Junction and [[Bathampton]] Junction and Track Circuit Block (TCB) working applied.

At [[Thingley]] Junction, all the semaphore signals were removed. On the Down Main, existing signals T50R and T50, installed in Stage 2, were renumbered T52R and T52. T52 was given a number 1 position light junction indicator, applicable to the [[Weymouth Line|Melksham branch]], and no more signals intervened between there and the facing junction (the semaphore Inner Homes were not replaced). The Down Siding was also removed.

On the Up Side, the Up Main Home, was replaced as a 2-aspect colour light T3 (same lever as its semaphore predecessor). The functionality of the Up Main Distant (number 1, and only a single arm, reduced from 3 arms at the closure of [[Thingley]] West in 1955) was replicated in a new colour light T3R (Y/G), 2240 yards in rear. The Up Starting signal was not replaced.

The Up Sidings were retained, with a position light ground signal at each end of the trailing crossover connecting them to the Up Main. GPL T43 replacing semaphore disc number 43, and GPL T33 (normally showing yellow/white) replacing several ringed-semaphore arms reading from the various sidings (numbers 8, 16, 17, 33). The long trailing crossover from the sidings to the Down Main, with a fixed diamond in the Up Main was removed (lever 28).

An additional signal was installed on the Down Main, west of the junction, DM97 (2A). This was semi-automatic as it protected [[Corsham]] ground frame. [Released from Bathampton??]

The [[Weymouth Line|branch line]], to Bradford Junction, was singled, the Up Branch, and associated fixed diamond in the Down Main and trailing point in the Up Main were all taken out of use. The Down Branch became a single line, up trains, leaving the branch, using the new trailing crossover installed in Stage 2 to access the Up Main.

Lever 7 (formerly a signal in the Up Sidings) was recycled to control two-aspect Distant and Home signals coming off the branch, T7 and T7R.

The block working on the branch became Electric Token Block between Thingley Junction and Bradford Junction, with the signals protecting the single line being released by withdrawal of a token for 'one train' (as opposed to 'one pull') only.

At about the 98 1/4 mile post the formation swapped sides. Trains from there to [[Thingley]] Junction travelled over the former Down Branch, and trains from there to Bradford Junction travelled over the former Up Branch.

New ground frames were installed to work siding connections at [[Melksham Ground Frame|Melksham]] and [[Holt Ground Frame|Holt]], released by the single line token. Intermediate instruments were provided at both ground frames, with telephones to Bradford Jn.

Although not on the Swindon panel area, as part of this stage of the scheme two auxiliary machines were provided at Bradford Junction at the Down Loop Starting and Up Branch Home (telephones to Bradford Jn). The loop between the Main and the Branch at Bradford Junction was also singled, the original Up Loop surviving to become bi-directional.

Back on the Main Line a new ground frame was provided at [[Box Ground Frame|Box]], to work a trailing crossover, protected by semi-automatic signals DM101R, DM101, UM101, UM101R. The existing connections at Corsham were worked by a [[Corsham Ground Frame|ground frame]], protected by UM101/UM101R on the up, and DM97 on the down.

[[Box Ground Frame|Box GF]] and [[Corsham Ground Frame|Corsham GF]] were locked by Annetts keys released from Bathampton Jn Signal Box, which also received telephone calls from UM101, DM101 and DM97.

Tell-tale wires already existed in Box Tunnel, these now being connected to [[Thingley]] Junction Box (pending the installation of emergency telephones "at a later date"). The siding connections into the east end portal of Box Tunnel were spiked, clipped and padlocked normal.

==Swindon MAS Stage 1 - Uffington to Highworth Junction==

The first stage of the Swindon MAS scheme was planned to be introduced over the period Saturday 12th November to Monday 14th November 1966 between [[Uffington]] and [[Highworth]] Junction.

As part of this stage of the scheme, [[Knighton]], [[Ashbury]] Crossing and Marston Crossing West Signal Boxes were all taken out of use, with all the signalling removed and the level crossings at [[Knighton]] and [[Ashbury]] temporarily closed pending conversion to AHB. [[Knighton]] Signal Box was planned to be taken out of use between 0700 and 0800 on Saturday 12th November, preliminary to the main occupation.

Continuous track circuiting was installed on both lines from [[Uffington]] to [[Highworth]] Jn, and track circuit block (TCB) applied between the two boxes.

[[Uffington]]’s Up Main Distant and Home and its Down Main Starting were all removed in favour of the new sequence of automatic signals west of the loops.

[[Highworth]] Junction’s Down Main Distant and Up Main Outer Advanced Starting were similarly treated. [Numbers??]

A new ground frame was installed at [[Ashbury Up Siding Ground Frame|Ashbury]] to control the trailing connection from the siding there named "[[Ashbury Up Siding Ground Frame]]". The [[Ashbury Ground Frame|existing ground frame at Ashbury]], controlling the emergency crossovers remained. Both ground frames were locked by Annetts keys released from [[Uffington]], the protecting signals were UM71 on the up and DM70 on the down.

On the Up Main, the MAS signal sequence, and number of aspects, was: UM73R (Y/G), UM73 (3A), with telephones to [[Highworth]] Junction SB. And UM72 (4A), UM71 (4A, semi-automatic, protecting Ashbury GF), UM70 (4A), UM69 (4A), UM68 (3A), UF22 (3A, entrance to [[Uffington]] up loop), UF16 (3A, exit from [[Uffington]] up loop), UM65 (3A) with telephones to [[Uffington]]). [[Uffington]] already controlled several more automatics on the Up Main east of the loops, since the [[Reading PSB|Reading]] MAS scheme.

On the Down Main, the MAS signal sequence, and number of aspects, from [[Uffington]] was: DM64 (3A), UF32 (3A, entrance to [[Uffington]] down loop), UF4 (3A, exit from [[Uffington]] down loop), DM67 (4A), DM68 (4A), DM69 (3A), DM70 (3A, semi-automatic, protecting [[Ashbury Ground Frame|Ashbury GF]]), with telephones to [[Uffington]]. And DM72 (3A), DM73 (4A), HW1 (4A) with telephones to [[Highworth]] Junction SB. [[Uffington]] already supervised several more automatics on the Down Main east of the loops, since the [[Reading PSB|Reading]] MAS scheme.

Telephones to [[Uffington]] were also provided at the handcrank release instruments at [[Uffington]] and the ground frames at [[Ashbury]].

As part of this stage of the scheme, [[Knighton]], [[Ashbury]] Crossing and Marston Crossing West Signal Boxes were all taken out of use, with all the signalling removed and the level crossings at [[Knighton]] and [[Ashbury]] temporarily closed pending conversion to AHB. [[Knighton]] Signal Box was planned to be taken out of use between 0700 and 0800 on Saturday 12th November, preliminary to the main occupation.

Continuous track circuiting was installed on both lines from [[Uffington]] to [[Highworth]] Jn, and track circuit block (TCB) applied between the two boxes.

[[Uffington]]’s Up Main Distant and Home and its Down Main Starting were all removed in favour of the new sequence of automatic signals west of the loops.

[[Highworth]] Junction’s Down Main Distant and Up Main Outer Advanced Starting were similarly treated. [Numbers??]

A new ground frame was installed at [[Ashbury Up Siding Ground Frame|Ashbury]] to control the trailing connection from the siding there named "[[Ashbury Up Siding Ground Frame]]". The [[Ashbury Ground Frame|existing ground frame at Ashbury]], controlling the emergency crossovers remained. Both ground frames were locked by Annetts keys released from [[Uffington]], the protecting signals were UM71 on the up and DM70 on the down.

On the Up Main, the MAS signal sequence, and number of aspects, was: UM73R (Y/G), UM73 (3A), with telephones to [[Highworth]] Junction SB. And UM72 (4A), UM71 (4A, semi-automatic, protecting Ashbury GF), UM70 (4A), UM69 (4A), UM68 (3A), UF22 (3A, entrance to [[Uffington]] up loop), UF16 (3A, exit from [[Uffington]] up loop), UM65 (3A) with telephones to [[Uffington]]). [[Uffington]] already controlled several more automatics on the Up Main east of the loops, since the [[Reading PSB|Reading]] MAS scheme.

On the Down Main, the MAS signal sequence, and number of aspects, from [[Uffington]] was: DM64 (3A), UF32 (3A, entrance to [[Uffington]] down loop), UF4 (3A, exit from [[Uffington]] down loop), DM67 (4A), DM68 (4A), DM69 (3A), DM70 (3A, semi-automatic, protecting [[Ashbury Ground Frame|Ashbury GF]]), with telephones to [[Uffington]]. And DM72 (3A), DM73 (4A), HW1 (4A) with telephones to [[Highworth]] Junction SB. [[Uffington]] already supervised several more automatics on the Down Main east of the loops, since the [[Reading PSB|Reading]] MAS scheme.

Telephones to [[Uffington]] were also provided at the handcrank release instruments at [[Uffington]] and the ground frames at [[Ashbury]].
