Ground frames at Cressage and Berrington don't match other sources...

Regarding the supposed groundframes for working the far end loop points at Coalport, Cressage, and Berrington until 1930, the situation doesn't seem to match Marshall's information...
Firstly, the Signalling Record Society diagram for Coalport shows the existence of the motor points at a later date, and given the distance to the signal box, I can believe that they were too far for manual control.
However, I can't find any evidence for a similar situation at Cressage and Berrington. A [http://www.s-r-s.org.uk/html/gws/S3032-2h.gif 1913 sketch of Cressage] shows the points at either end of the loop being directly controlled from the signal box in standard fashion. The similar [http://www.s-r-s.org.uk/html/gws/S3029-2h.gif 1913 sketch of Berrington] doesn't show lever numbers, but equally there's no sign of a ground frame or any other unusual feature.
On the other hand, I can't get the distances in question to match the supposed maximum distances for operating points. Using OS maps, I get the distance from the signal box to the far end points as 350 yards, which was only permitted for manual operation after 1925. For Berrington it's about 250 yards, which you can do from 1908, so possibly in the 1913 diagram but not the original date of the box.
An odd situation! --[[User:Danny252|Danny252]] ([[User talk:Danny252|talk]]) 18:25, 13 December 2015 (UTC)
