Another DMU picture from 1995. Bishops Lydeard. Cravens DMU was working the 1200 shuttle to Norton Fitzwarren . This unit was a resident at the WSR for a only a short time.

Par Signal Box - a brief history of
Roy Hart
The box opened in 1879 when the Cornwall Minerals Railway (by then controlled, but not owned by the GWR) opened a new double track link from St Blazey to Par. The CMR was, of course, standard gauge, while the GW main line was broad gauge from Exeter to Truro.
As opened, Par box was 19 feet in length (a glance at the back of the building today reveals the brick flue of the longgone stove: this was at the centre of the original structure). As opened, the box would have had a frame of about 20 levers, controlling very basic signalling on both standard and broad gauge.
The main line layout (i.e.the broad gauge) was very basic: just a refuge siding at either end of the station and a crossover road midway along the platforms. The platforms were much shorter then and the box was free-standing, some way from the platform.
At the eastern end was a broad gauge siding which curled behind the platform to terminate in the goods shed. The goods shed also had a standard gauge track to facilitate transfer of goods.
With the conversion of the gauge in 1 892, the basic layout at Par was unaltered, but signalling was new and much more elaborate: this required a new lever frame of about 40 levers. This meant that the box needed to be extended at the western end to a total length of 38 feet.
With the track layout unchanged from the past, operations could be very difficult. There was no direct connection between the down main and the branch, for example and down trains had to perform a reverse shunt in order to reach St Blazey. At the west end there was no link at all.
All of this was finally resolved in 1913 when the layout was comprehensively remodeled. There were now compound crossovers at both ends of the station, linking branch to main. The box also acquired its third (and last) frame, of 57 levers, equipped with 3-bar tappet interlocking.
The second world war brought further change: in the run-up to D-Day vast amounts of materials were shifted to westcountry ports and rail facilities expanded to cater for it. At Par the down refuge siding was extended eastwards to form a goods loop and 'calling-on/ arms were added to three of the up branch and main signals to ease the combination of trains from branch and main for the journey east. The new goods loop was even provided with a water column, for wartime freights were often trapped in such loops for hours at a time.
The frame was relocked in 1943 with 5-bar tappet locking, full track circuiting was installed, together with an illuminated diagram (it survives, though much-altered, in the box today). The end of steam brought inevitable changes including the loss of local freight. The old goods yard was cleared and replaced by a short-lived container freight scheme.
In 1974 the layout was remodelled and simplified, losing no fewer than five compounds and diamond crossovers.
The most significant change in the postwar era was in 1986, when Burngullow box was abolished and the line from there to Probus singled, controlled by a miniature panel at Par. This act of breathtaking corporate folly had to be put right when double line was reinstated (at vast expense) 1 5 years later.
Par signal box closed in 2024 after 145 years of service - not a bad innings!
The structure is listed grade Il by English Heritage.
