I'm sorry, I hope I'm not boring you with this, it's just I don't know where else to ask for this kind of information. My question is about signal FG18, the shunt signal on the westbound main, west of Dagenham East. It allows wrong-road moves back into Dagenham East via a mainline shunt from platform 1. It has a theatre route indicator capable of displaying - I believe - two routes. Presumably one into the bay road and one into platform 2. My question - just to be sure - is which is which? Does it show (as I suspect) 1 for the route to the bay road and 2 for the route to platform 2, or is it the other way around?
I only ask because it's a handy example and I remember reading the numbering is 'from the left,' which I take to mean that 1 should be the leftmost route, although I may be mistaken.

Yes, 1 for the bay, 2 for the EB. These are read left to right.

The 1st route is always the one furthest to the left

Okay thanks! Presumably that's true even if the it goes against the logic of the platform numbering? (So you could have 1 for platform 2 and 2 for platform 1 in principle?)

There is a 'sort of' principle for platform numbering but there are many discrepancies, mostly because of historical reasons. The "general rule" is 1 WB/NB and 2 EB/SB but as you can imagine, it opens a big can of worms. Let's say I'll leave it at that for now ......

Yes - as stated, theatre type route indicators are always read as route 1 furthest to the left on LU. For completeness, National Rail is different. Routes tend be shown as letters (F = fast, S = Slow, D = Down/District, U = Up, etc). Where platforms are involved, they do use the actual platform numbers. |

Its not just theatre signs it also applies to main running signals with junction indicators.

NR also denote their routes differently - they use A,B,C etc where we use numbers. |
