APT advanced passenger train, developed in the 80s before the technology was sold to Italy and we end up with the pendos

LOWS locally operated warning system, the lookout( might be round a corner) has the controls to warn the gang

Tecnically you are right with the first two, but I was looking for something slightly different. (Think track)

SPT signal post telephone

A big gold star for you royaloak They were indeed what I was looking for.

PeeWee is a lookout alarm system that's so named due to the noise it makes. No longer used IIRC. ATWS is a warning system of alarms and lights activated by a treadle system. TOWS is the equivalent track circuit operated system. Both are used at fixed locations. ATWS systems can be temporarily set up at long term sites however.

 

[driver9000]

DSD, i think is a some kind of driver vigilance device?

DSD - Drivers Safety Device.
A pedal which the driver must keep pressed while the train is in motion (some older stock has it incorporated into the power handle). The Vigilance device if fitted is incorporated into the DSD and if no major control (power, brake, AWS) is moved for approx 60secs, the alarm sounds and the driver must acknowledge by releasing the DSD and pressing it again otherwise the train is brought to a stand automatically.

AOCL it should be, Automatic open crossing, locally monitored.

 

[O L Leigh]

ADD - Automatic Dropping Device
Automatically drops the pantograph if it becomes damaged (e.g. loss of carbon strip or pan head) or goes over-height.

AOM - Area Ops Manager
Someone further up the ladder than me.

S&C - Settle and Carlisle...?
Too easy...?

C&W - Dunno

CWR - Continuously Welded Rail
Should be self-explanatory.

DSD - Driver's Safety Device
Not like vigilance at all, though vigilance can be incorporated into it. It's like the deadman's handle of old, though these days it's more likely to be a pedal.

AOLC - Shouldn't this be AOCL...? Automatic Open Crossing Locally Monitored
An open level crossing (e.g. one without barriers) operated automatically by treadles or by a driver's plunger, that is not under the direct control of the signaller. Traincrew are required to observe a flashing white light on approach to the crossing to see that the crossing equipment is operating correctly.

ATOC - Association of Train Operating Companies
Kind of a trade body that represents passenger train operators.

CDL - Central Door Locking
What stops the doors on slammers swinging open.

COSHH - Control of Substances Hazardous to Health
Rules and regs for looking after hazardous substances.

DOO - Driver Only Operation
What I do.

SPT - Signal Post Telephone
Direct comms with the Bobby at the signal.

Very good O L Leigh. The missing one was Carridge & Wagon...basicly someone who is trained in viehicle inspections.

[Muttley]

How about...

1) ROTTEN
2) PAINT

 

[Wyvern]

RRI is route relay interlocking - signalling again

What about RRAP?

PAINT and ROTTEN You're sure you haven't made these up?

Acronyms always remind me of Tommy Handley and ITMA - any guesses for DWTWWASBE?

 

[Trog]

RRAP =Road Rail Access point

LWR? and how long is it?

 

[Hydro]

Long Welded Rail, 709ft nowadays isn't it?

 

[Trog]

No 709ft is CWR.

LWR and CWR are actually not quite the same thing.

 

[Hydro]

Always though LWR was CWR prior to welding up. I'll throw in 120ft.

 

[crazytrain_uk]

Ok anyone know these two?

MINT

CLOVE

Should sort the (old)men from the (new)boys

 

[Trog]

Always though LWR was CWR prior to welding up. I'll throw in 120ft.

Long Welded rail is rails greater than 60'-0" in length, but not greater than 180'-0" in length.
