Abbreviations on railway coaches

[TiggCJ]

Hi All,

Just wondering what certain abbreviations stand for. These are located on the chassis at the end of carriages and under the doors (specifically on the Class 357 EMUs).

The abbreviations are:

. M.R.P.C.C
. A.S.I.C
. D.S.I.C
. C.E.T.I.C

These are all of the ones I've spotted so far. Are there any more?

Any help would be most appreciated!

Thanks,

TiggCJ

Are you sure that the first one isn't MRPIC? (Main Reservoir Pipe Isolating Cock)...?

Other ones are probably (unless there's some traction-specific differences) Air Suspension, Door Supply and Controlled Emission Toilet isolating cocks.

I think the abbreviations are to do with train brake pipes/cables etc

I'm intrigued too! I've noticed MRPIC on 185s, which makes me think of Manchester Piccadilly - which I presume is a red herring!

EDIT: dealt with above, thanks!

Homework ?

Main Res Pipe Coupling Cock
Door Supply Isolation Cock
Auxiliary Supply Isolation Cock
Air Suspension Isolation Cock

CET sounds traction specific

Compressor ?
Chemical Emissions Tank ?

MRP IC and MRP CC are different, but not by much. And yes, there are many more...

 

[Tomnick]

Is MRPCC just a traction-specific equivalent to MRPIC, or does it perform a slightly difference function on units with both MRPIC and MRPCC?

CET is the Controlled Emission Tank, isn't it? (As in toilet waste....)

Slightly different function. Its so slight its hardly worth having two names for it. Mr Pic is what most people I know call it. On some units I think its even called the ECIC !

@thebdiboy. Cheers, that's what I meant, honest Guv. No idea wht it has an isolation cock though. Ours just has a cover (if its still there) and its sucked out. I might have a look see next time I'm below solebar level.

I believe mrpic isolates normal flow of air between the bsi couplers (traction specific) and the ecic is actually not an isolation cock as such, but an application cock, in the you need to activate it to couple up in emergency situations ie standard bsi coupler train rescued by an 08pilot for example. The air is provided though a hose connected though ecic

 

[Tomnick]

Certainly on the 15x fleet, the emergency air connection seals itself when there's no hose connected, so the ECIC only needs to be used to isolate the supply if it's damaged or otherwise not sealing properly. Some are left in the 'isolated' position normally though. Is MRPCC equivalent to this then?

Ecic still has a cock on 15x but his normal position is isolated. When Schrader hose connected you then un isolate it. Could be different in your area?

It's just 153s that have the ECIC normally 'normal' here, 156s and 158s are all normally 'isolated'. It shouldn't make a difference either way though, as long as the hose connection isn't damaged!

 

[t_star2001uk]

ECIC is also on 165's and 168's.

 

[ComUtoR]

We have MRP CC on a Brel and MR IC on a Metcam MR PIC on a 319 All do the same job (not to be confused with the other MRIC)

ECIC/ASIC/ESIC Different names, same job. (not to be confused with the other ASIC)

 

[TiggCJ]

So, what does ECIC and the other MRIC stand for?

 

[DasLunatic]

CET is the Controlled Emission Tank, isn't it? (As in toilet waste....)

CET is also the station code for Colchester Town, which has nothing to do with emissions, except when the bog is blocked.

 

[Tomnick]

So, what does ECIC and the other MRIC stand for?

Emergency Coupling Isolating Cock (as above, isolates the air supply to the emergency air - Schrader - hose connection) and Main Reservoir Isolating Cock (isolates the main reservoir on a vehicle from the rest of the air system, so it'll be relying on the pressure in the main reservoir pipe being maintained by adjacent vehicles).
