OTT

The statement caused much confusion to drivers at the new signalling arrangement is a bit over the top.

The accident occurred because one driver went through a red signal. This could still happened on a convential double track junction. The single lead junction does increase the chance of a collision if a driver does a SPAD, but neither does a double junction eliminate all risk.

Aftermath

According to reports The configuration adopted for this particular junction was unnecessarily constrained and was strongly criticised by contemporary commentators (Hall 1999), and was altered immediately afterwards.

But how was it altered? Back to the original low speed double junction with a diamond crossing or a higher speed double junction with a ladder crossover?

Diagram

The diagram given in the article does not represent the junction arrangement as it existed at the time of the accident. The second edition of Quail maps, published in 1993 - page 7 - gives the track layout of the station environs. The accident happened were two bi-directional lines met, prior to become double track through the platforms.

As can be seen the track layout was more that a single lead junction, several bidirectional single lines had been created when the junction was redesigned (two at the west end and one at the east end). The revised layout (in the 3rd edition of Quail - 1996) re-doubled the line from Kirkhill into the station.

I do not have the tools to create a replacement diagram(s), can someone else oblige. --Stewart^(talk) 18:40, 21 July 2008 (UTC)[reply]

Microsoft Word has a simple Draw program which was used to create the diagrams in Double junction. Tabletop (talk) 09:18, 2 April 2009 (UTC)[reply]

Impact

The head on impact is not the sum of the two speeds. For each train, it is their respective speed. DMBanks1 (talk) 21:57, 3 June 2020 (UTC)[reply]
