Could someone clear up something which has bugged me for years, please? Travelling around on the Central during the 60's, I'm sure there used to be warning signs on the cable bridges around Newbury Park-Hainault which said something like "danger-carbide of carborundum". I never did understand what it said, and as a kid I probably never read it properly either! Can anybody shed any light for me please?

Don't know about PWay & signals,but rolling stock staff used carbide lamps until the 70's.

Didn't you tell a story once about a carbide lamp that was left unsealed inside a tightly closed tool locker, and the resulting emissions caused the locket to explode when a 62TS DM motored away using the shed leads, generating sparks in the process?

That's right,carbide mixed with water makes a very explosive mixture,although the lights used to be very bright esp if you got one of the guys who religiously polished the brass reflector.

Don't know about PWay & signals,but rolling stock staff used carbide lamps until the 70's. When I started on the signal department in 1977 we used Tilley paraffin lamps as did the P-Way. The P-Way really used to shine their reflectors so you could see them coming for miles at night especially in the tube tunnels where a glowing ring preceded them before the walkers were actually visible. There always seemed to be something rather holy about that although many might say ghostly! |

Hmmm this is jogging memory. Didn't the signs read "CAUTION - CALCIUM CARBIDE" in upper case white-on-red Johnston typeface? It was a real shame when those hissing yellow-tinged tilley lamps went.
Reminds me too of the standard "IN CASE OF FIRE TELEPHONE LINE CONTROLLER AND SIGNAL REPORT CENTRE ON AUTO 188" or similar that were on IMR/relay room doors. Still there in many cases but reversed after the Line Service Centres (now Fault Report Centres) were introduced c.1992.
