I spotted the following at Earl's Court over the weekend...  Anyone know what the H OFF means - I know D is de-icer, but we couldn't work out H and why it was so prominent on the platform. |

The OFF means the associated signal is Clear and the H presumably refers to Hammersmith

The sign is an old one that is no longer relevant - it applies to train heaters and is telling staff whether they should be on or off in the same way as 'D' boards tell staff about de-icing equipment.

Very good point. Always happy to be corrected - and therefore learn.

Cheers Colin - I suspected you might be along to give the answer...
Although, I'm not sure I like the concept of drivers being told to turn the heating off -- was there a reason?

Heating isn't needed on a hot summer's day. Presumably there is or was some benefit to turning the heating off in situations like this.

In the same way as the 'official' leaf-fall season runs from 'X' date to 'Y' date each year so did the heating 'season'!
So, in the days of Guards a notice would appear in the Traffic Circular effectively saying Winter starts on 'this' date. Guards would then be expected to switch the train heaters ON during this period.
When there were warm days during this time, 'official' notice to switch them OFF was displays using the signs.
With the advent of thermostatically controlled heaters on D Stock (and i believe refurbed C Stock) there is now no need for the signs.

Well, since it's no longer in use; let's go "preserve" the sign... ;D  |

Of course the "H-OFF" signs were double-sided with "H-ON" on the other face and were turned as appropriate.

I saw a similarly curious sign at Wembley Park on the Jubilee - R OFF.
Anyone know what this means?

I wondered if it meant heated current rails.
