SN.30
Back to Control Functions.
Origin
...
The signal is on the Down Goods Siding, just east of Swindon. It protects a trailing connection with the Down Through Siding (worked by the Down Siding Ground Frame), and the facing connection towards the Down Main.
Drivers of trains at a stand at this signal were expected to shut down their engine, as the houses in Station Road backed onto the line here.
Alterations in connection with new Platform 4
This signal was marooned on a section of line that was temporarily out of use between 0800 Wednesday 9 October 2002 until 0600 Monday 4 November. The Down Through Siding and Down Goods was out of use from 76m 70c to the west end of the station to allow alterations in connection with the closure of the Down Goods and building of the Down Main platform.
On Monday 4 November the line was reopened between 76m 70c and a new buffer stop at the London end of the former Down Goods. The line beyond the buffer stop to the west end of the station having been lifted (since 1st November). SN.30's former main aspect route to the Down Goods, SN.38, was abolished, and the position light route now read to the buffers.
Alterations in connection with the removal of the Down Siding Ground Frame
The signal lost its position light indication when the Down Sidings Ground Frame was removed, and no signalled routes into the spur remained. The Down Main is not permissive.
