Does any one know if this is currently in anybody's plans? At present the point rodding at Tunnel Junction is being renewed. Some similar work including a new yellow disc signal was done at Shrub Hill last summer.

The new signal will be a fog piercing LED so is likely to be more conspicuous to drivers .

That's a lot of signals for a driver to miss in un-pierced fog . . .
Now if it is renewals necessary through old age, or demands of a changed train service, that would be a more justifiable excuse but business-speak such as that doesn't wash with me.
(Yeah, yeah, I know it isn't called Rule 39 now)
Interesting - thanks. Will the new C/L be controlled only from SH, or will TJ retain a slot on it too?HighlandRailwayman wrote:That is indeed corrrect, as a SPAD mitigation measure, SH2/3 and TJ6 will be combined into a single R/Y colour light (with cats eyes for the draw ahead move) and moved back in rear of its current location to enable an unrestricted acceptance at SH (providing the 'overlap' track is clear) Design for this and various other minor modifications for the malverns life extension is ongoing currently (including the removal of the lock and block between malvern wells and ledbury) and a re-lock and re-furbishment of the frame at SH - believe the blocks for all this work are booked for middle of 2016
Thanks - that sounds like it makes a lot of sense.HighlandRailwayman wrote:From memory it is being moved about 60 odd meters in rear of the current SH2/3 and will be slotted by TJ6.
