Class 185 - blinking CDL light

[nathanclass323]

Sat on platform one at Sheffield at the moment and a 185 stopped on platform two. I noticed that the rear car CDL light was blinking. Does anyone know why?

Thanks.

What's a CDL?

 

[MCR247]

On desiros the light blinks on the carriage where the door control panel is active

CDL = Central door locking

 

[nathanclass323]

Ahh. Thank you!

ODIL is an Outside Door Indicator Light

In other words, it's where the guard is and it's a feature I think all new built stock should have!

Just to be mildly pedantic, it's a Hazard Light on a unit Though I must confess ODIL is a new one on me, perhaps somebody somewhere has decided to make up a new acronym?!

CDL refers to HSTs and coaching stock with slam doors, to which secondary door locking has been fitted in the form of CDL bolts (the primary 'lock' being the door handle and catch mechanism, which of course keeps the door closed but doesn't actually lock it in the normal sense). Units fitted with automatic doors don't have a 'central locking' system as such, as the doors lock by virtue of being closed.

SWT Desi's also have the flashing light feature, presumably it's standard on all of them?

The flashing light or the guard? I'd vote both.

+1!!

In pretty sure this is the case.

+1!!

+2!!

Officially its called a DOL - door obstruction light. It lights up when door interlock is lost but also can come on for other reasons such as a pass comm activation, fire bottle discharge, track circuit actuator failure and a few others.

I here I thought it was called BIL, Bodyside Indicator Light!

That is definitely a new one! Must be a north of the border term

 

[scotraildriver]

Ok - the 158 traction manual calls it a DOL and the 170 manual a DHL

 

[185]

Have been times when if operated from the GOP (middle car guard panel) where staff:-

Close doors, (on button)
Key out to close local door, (using t-key latch)
Key in to keep stop buzzer active should it be needed.

.....and as the train sets off, the external hazard light is flashing until 5mph!

Technically means despatchers should stop train, however most are now used to this phenomenon.

 

[driver9000]

I've only ever known them as Hazard lights as they aren't just to indicate door release. The Rulebook certainly calls them Hazard lights, must be a regional thing to call them other names.

I've never noticed the hazard light flashing on a 185 as it sets off.

 

[nathanclass323]

Oh I have.

I always knew Odil as an LU term.

I've certainly noticed it on TPx and LMR Desiros.

As for whether it's a good idea or not; I am not so sure as it still remains lit even as the train is pulling out of the platform, so not sure how you can tell whether the doors in that car which the Guard is in have got interlock or not.

 

[185]

Flashing light is to indicate a keyswitch on (live panel).

As the train goes over 5mph, there is a distinct click (like a black cab taxi!) where the circuit breaker de-energises and the hazard light & guards panel switch off.

Only works for the Guard but there's a door interlock light on the Guard's panel, so the Guard would know once the cab door is shut.

In Southern land we also know them as BIL lights and flashing one on 377's indicates a pass comm activation rather than the location of the guard...just to be different

I'm with you here on the 'Hazard Light'

Sure I've heard it called an External Fault Light as well in places.

 

[thelongestroad]

Well everyone I know calls it the door kicking light.

Giving my age away with 2-BIL being one of the Southern Railway units.

 

[atwales]

It could just be regional preferences, like the signal bells are different all over the country.

Most trains to the west of England have a proper buzzer for a signal bell.
London units such as Southern's have a high-pitched bell (slightly more posh)
HST's especially have a sort of monotone beep.

I think it's all these terms are regional..

 

[jopsuk]

Surely what the external light is called is somehwat dependent on it's function- pretty clear from this thread that they do different things on different stock, even on modern units.
