Origin

DM.70 was a 3-aspect, semi-automatic signal commissioned at Swindon MAS Stage 1 on 14 November 1966[1]. At that stage it was supervised by Uffington SB.

It was the protecting signal for Ashbury Level Crossing and Ground Frame on the Down Main.

Controlled passed to Swindon Panel under Swindon MAS Stage 5 on 3rd March 1968.

Conversion to Controlled

This signal was planned to be converted to a controlled signal (SN.18) (from a semi-automatic) on 2 August 1970:

But the work did not take place as planned:

and the signal was actually converted to SN.18 on 6 September of that year.

Conversion to Automatic

Latterly the signal was converted back to an automatic.

Upgrading to 4-aspect

The signal was re-fitted with a 4-aspect head at 04.50 on Monday 28 January 2002, although the top yellow was not brought into use.

The top yellow aspect was planned to be brought into use on 7 February 2000, as described in GWS.15, but, due to 'construction difficulties' the work did not take place.

The top yellow was then planned to be brought into use on 11 February 2002.
