TD berth contents for non-train use

Unread postby rower40 » Tue May 9, 2017 10:08 am

It's quite common to see "-T3-" or "3187" or "BLOK" in a TD berth, indicating the line being closed for some reason or another. Sometimes signallers put in the departure time of a train into a platform berth.

Two questions:

1) Would readers like to list some of the more unusual TD berth sightings they've seen over the years?
2) What does "POTS" mean? Currently at Shenfield Sidings, and Southend Victoria Down Sidings South (Courtesy of Opentraintimes TD maps). I've seen "DETS" indicating that Detonators have been put down.

Thanks...

Doubtless far from unusual rower40, but remembering back about 20 and more years : -

P0SS (Possession)
ST0P or -N0- (no trains this way; possession commences somewhere ahead)
1S0L [also perhaps BTET] (Blocked To Electric Trains {'Isolation'} )

And no doubt various messages have been interposed in two or more berths along a line signifying a box closure; e.g. GOOD BYE-
BZOH

Whilst not quite in the manner of what you're seeking, I remember when I was assisting the testing of Chester PSB (before commissioning) that during a particularly quiet spell on the panel in the middle of the night, someone put in YAWN to an adjacent - open - fringe signalbox. A few minutes later the signalman replied ZZZZ.

Happy days,

Mark

I saw "TREE" on the down slow line west of Winchfield (SW main line) on a particularly windy day in February. It meant exactly what it said!

Along the same lines, the Carlisle portion of the London-Scotland sleeper was always berthed in Platform 8 at Citadel and from the day Carlisle PSB opened they were described as ZZZZ on the panel.

Sometimes I have noticed what appear to be peoples names - I'm guessing the PIC's?

I recall that during the flooding at Blackfriars (last year?) two berths showed
AQUA and
PARK respectively.

Also, when the Eastbourne area was resignalled, there were a number of 'farewells' displayed in the berths by last signalman on duty in the various boxes. I have kept some (rather poor, but readable) screenshots of these.

Except that it doesn't of course. It doesn't signify or prove a thing. Which is why all such things written in describers is unofficial and potentially confusing or dangerous. It isn't unknown to see "DETS", "TIII" and other supposedly non-moving things move from one berth to the next - just a trolley placed on the line in a possession is enough to do that.

Are you sure? That would be remarkable as Blackfriars is above the river.

Returning to Rower's question -

What does "POTS" mean? Currently at Shenfield Sidings, and Southend Victoria Down Sidings South (Courtesy of Opentraintimes TD maps).


I started interposing "POTS" in various berths at Bletchley Yard during the remodelling there a few years - a reminder that there was a "Possession Of The Sidings" - I also used "SPOS" sometimes - "Siding POSession".

Feeling flippant one day I put "POTS" and "PANS"!

This was a novelty for me as it couldn't be done with older relay based TDs.

Somewhere around there it was. Water main burst, I think.

The engine sidings next to New St PSB where the electric locomotives used to stable had RUST in their TDs berths.

Amongst others I've seen not already mentioned are SHUT, NOGO, NODC and SHED after one blew onto the line

Yeah, we use the TD in this way regularly at Motherwell, -T3-, -LB- or ITEM --7- for example, purely as a reminder of whatever is going on, RUST is another one on lightly used bits such as the Whifflet Basin, another one which may be seen is STAF GONE HOME at Motherwell TMD meaning that the depot chargeman has called in to say there is no one on duty and the derailers have been lowered etc.

It's been a common occurrence in many boxes for years, obviously a little known practice to outsiders until NR started sharing TD data, when I started in Motherwell 20 years ago you couldn't do it with the old TD, not long after the current Vaughan Harmon system was installed where you could do it.

I once took a call from a hysterical train running controller at the TOCs control room demanding to know, and score points by pointing out to the world, why I had signalled a train through an engineers possession (T3)................

So, TREE, BUMP, BTET then SHNT (shunt) or WASH for stuff headed to carriage washer, and where there are back to back possessions it's common to put the item number as it appears in the WON.

"Why have you signalled our train through the block" demanded the TOC controller ??"
'Eh
"At Harpenden 1T21 has been put into the block, i'll have to report you........."
Eh'
Think you'll find thats IT21 (item 21) my old fruit............................
" O'h - click

And as to the AQUA PARK... North of Farringdon on entry into Clerkenwell #1 Tunnel http://bed-pan.homestead.com/IMG_4668.JPG
