[[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]].
