Talking to someone the other day about COIFs, he quoted RT1; they fitted flashing indicators as a safety issue. the nearside lens utilised the side light lens on the nearside bulkhead. the Certifying Officer didn't like it because it was too far back. Had the bus not been fitted with flashers, it would not have been a problem. Why fit stuff you don't need?

My bus number (if any): RML2532

None of this is up to me, it's customer requirements. Personally I couldn't agree more.... if it wasn't needed in the 1950's why is it needed now?

I'm not sure about future psv usage, it is probable though and that's where the passenger door comes in (originally open steps), I'm just guessing here but a conductor on a 31 seat bus may be uneconomical? I do intend to follow the universally accepted warning light colour codes, it makes life simple for everyone. I dismantled an RT flag unit today and with the valve and spring out it's almost ready made to fit a solenoid, the flag is actually quite light on the pivot pin so it should work out ok.

It's a post war PS1... vac front/vac mechanical rear, 25-30 in/Hg.

I've only had one indirect encounter with the COIF (Condescending Oaf Incites Fury) test. On an RF ten items were cited as grounds for failure and only one was legitimate, six were laughable, two were debatable and one more was a consequence of a lack of knowledge on obsolete tech.

I've had battles with the COIF officer on Rt tyre sizes, RF emergency door valve position, height of RF steps..

Like I said earlier, watch this space for COIF news.
