Was VERY bored last night, so I had a go on BVE, and jotted down all signal numbers from Edgware > Kennington (Ch X branch)
Anyway - you seemingly have ''FNX'' prefixed randomly onto the certain signals....
What's it mean ( or what area does it stand for?)
From what I can remember (I dont have them in front of me at the moment), FNX85 is Tottenham Ct Road's starter signal?
There are a few ''FNX'' signals too, on the run down to Kennington SB.

Similarly, we have FDX signals on the District. I believe other lines have similar, with the second letter being the first letter of the line name.

So, I'd imagine F stands for Floodgate, and if the middle letter stands for the line, does that mean X stands for signal?

"X stands for -"
- - 'X' Signal - An Automatic signal that must not be pased at Danger without authority.
(Imagine a FNX signal at Danger protecting a Flood Gate being tripped and passed by a driver when, suddenly
"WHAM!!!!" )

(Imagine a FNX signal at Danger protecting a Flood Gate being tripped and passed by a driver when, suddenly "WHAM!!!!" ) Also....... Normally the last signal before a Semi Automatic area is an X signal, so that trains can be held away from areas where there are points. Otherwise if there wasnt an X signal, and there was for exmaple a failure of some sort, the train would be tripping past the signal after 2 minutes and further locking it up...... So, I'd imagine F stands for Floodgate, and if the middle letter stands for the line, does that mean X stands for signal? You can also have a P-- signal, which is for a posession, they use it to control what goes into the posession, as the signal remains at danger because a track is dropped |

Wrt flood gate signals, they also carry an illuminated 'A' which denotes that they can be treated as an automatic signal. The 'A' is illuminated when the gate is not closed/being closed but goes out when the gate is in operation/closed.

The 'A' is illuminated when the gate is not closed/being closed but goes out when the gate is in operation/closed. That leads to the question when the last time an 'A' went out on the network (not including when the bulb failed!). Do the floodgates get operated ever for testing? |

I am not aware of any flood gates that are operational at this time, they were all taken out of commission some years ago (could be wrong though!). The Thames Barrier effectively made them redundant.
There is a really impressive one just east of South Kensington Circle/District platforms at the tunnel mouth. It's a huge gate on huge metal runners either side of the tunnel that sits permanently up in the air, amazing to look at. Maybe it's just me!
With the water table rising in London and the Thames Barrier looking like it will start to over top in the next decade it may be prudent to start giving them a bit of TLC! ;D

There are floodgates at Canning Town Portal on the JLE but these would only be used if the Lea floods.

The Floodgates at Canning Town on the Jubilee Line are in full working order.
