Description
This signal is the last on the Down Main before Swindon Station and protects all the connections at the east end of the station.
The signal shares its large overall gantry with SN.628.
Adjustments
SN.28 had a route, with a number 1 junction indicator, towards the Down Goods. The route was made unavailable with the removal of 335B points at 05.15 on Monday 25 February 2008.
335A points and the number 1 junction indicator on SN.28 were finally removed permanently at 05.15 on Monday 21 December 2011:
Shunting behind SN.263
In 2009, 332 points were re-layed 100 yards nearer to Bristol, reducing the standage between SN.263 and SN.28 to 6 SLUs (130 feet). A box instruction was added requiring that when a shunting movement was to travel towards SN.28 to reverse behind SN.263 then SN.28 must be off, to remove the SPAD risk of a drive believing the loco(s) would fit in between the signals (where they previously would have done).
