Warning Flashes


Recommended Posts

Can anyone tell me when the new style triangular warning flashes first appeared?

 

I'm looking to find when they were first introduced and what was the "legal" timescale for train operators to switch. Finally, did people tend to switch ahead of the deadline or was there still a lot of stuff around right up until the last moment as it were?

Looks like I'm going to be backdating some stock then! The joys of sectorisation to privatisation!

 

Stop, stop, stop! The Group Standard refers to the lineside signs. I know nothing about the rolling stock signs.

1998-ish was roughly the time when the new style flashes first appeared, although they may have started appearing in 1997.

 

HTH

 

I would agree with that, the very first batch of Coalfish for example had the older ones on, I shot one in 2004 which still had them so the occasional bit of stock later than that with a wrong one on is believable.
