On a rail transport system, signalling control is the process by which control is exercised over train movements by way of railway signals and block systems to ensure that trains operate safely, over the correct route and to the proper timetable. Signalling control was originally exercised via a decentralised network of control points that were known by a variety of names including signal box (International and British), interlocking tower (North America) and signal cabin (some railways e.g., GCR). Currently these decentralised systems are being consolidated into wide scale signalling centres or dispatch offices. Whatever the form, signalling control provides an interface between the human signal operator and the lineside signalling equipment. The technical apparatus used to control switches (points), signals and block systems is called interlocking.
This is the now obsolete one at Glenfinnon in Scotland
Another fantastic night in the Tetons! Last night we went up to Signal Mountain to see a stunning display of stars. I found it fitting to 'signal' the Andromeda universe, a satellite joined in for the fun too.
I'll be leaving the area soon, still undecided where to go. I have a few weeks to explore before my next workshop back in the Tetons (still some space left btw)

Moving at 60 MPH, an 8 car UP business/passenger special heads east with a brand new Tier 4 ACe leading the way.
URR 23, 22, 25, 16 lead the empty 66 coke train from Port Perry/Dexter yard are arriving back home into Clairton passing the C1 signal. 66 job ran on two shifts, they would run loads from Clairton to Braddock and to the CSX at Dexter yard. The midnight job would always take "dinner" at coal valley just north of Clairton until around about 7-730 and would then roll down into the mill to yard their train and tie up at 10am. Here the mid night train is running late and is rolling into the mill well behind schedule and would die while yarding the train.
LAL 423 and B&H 416 pause at the traffic signal at Painted Post to wait for the lights to change and allow them to head over to the NS to begin 'the dance'
Oh No ! Bentley Heath Signal Box is being ripped apart like a Christmas Cracker, with little respect for the yaers it has stood there guarding Mill Lane & The Railway.......10/02/2008

Now a thing of the past, I wish I had photographed these more and the others along the line for that matter.

This one is marked "Patented July 21 1903"
The north track of CN's Chicago Subdivision has been removed between Oakwood and 21st Street, leaving 16th Street Crossing a bit less cluttered and this signal guarding nothing. Behind it on the St Charles Air Line, Amtrak's southbound 'Illini' clunks across Metra's Rock Island District.
On a hike to Yant Flat north of St George, Utah, the view north to Signal Peak with its remaining snow caught my admiration. Signal Peak (10,369') is the highest point in the Pine Valley Mountains.

After decades of valiant service, the original Wabash southbound signal at Lodge was officially turned, cut, and shutdown forever. Rather unceremoniously, the heads were all turned and the wires that connected the signal to the relay cabinet were cut and stripped. 150 yards to the south, the "new" signal has been finally turned to face the tracks after having been installed nearly two years prior, and testing of all the indications is underway.
The reason for this change is visible on the left. The relay cabinet and the rollercoaster of codeline were deemed unnecessary - and potentially more costly to utilize - so the signal was moved back in order to condense the Lodge control point. Of note is that the codelines primary purpose here is in fact power supply, not the actual signal to the signal.
So, big whoop, right? A searchlight replaced with a searchlight. Fair trade, no? In a way, yes, and really nothing changes that much. But the replaced signal was a piece of the lines history. Formerly known as the Forrest District under the Wabash, the signals at Lodge date back until 1959 at the latest. There's something to be said about comparing the swap to the ship of Theseus - if all the rest of these searchlights were replaced with different ones, would it really be exactly the same?
At any rate, the fate of the Lodge 3-header has not been kind. We had hoped to acquire the whole signal and preserve it, but alas, when I asked about it the morning of, I was told we wouldn't be able to buy it because they were desperate for the parts inside.
The bright side? These parts salvaged from this signal will help keep the rest of the Bloomington District signals going - I asked about the rumour from earlier this year and it was confirmed false, the rest of the searchlights are not coming down in the foreseeable future. The day they do, well, that's when the preservation efforts can really begin.
Two hours after this photo was taken - while I was at work - the signal was pulled down, alongside the relay cabinet that housed the troublesome battery that was half the cause of the signals removal, and placed on a trailer. The trailer would be left overnight. A reliable source confirmed that they had already stripped the Lodge signal of its internal mechanism, reducing the entire signal to a thousand pound shell. Now, the signal is gone forever.
ROG Class 37 No.37800 "Cassiopeia" comes off the relief freight line at Hereford onto the Down main passing the impressive Hereford signal box. This is the 5Q79 Barton Under Needwood to Landore unit drag comprising TfW Class 175 3-car unit No. 175109, with 37608 at the rear.
Shrewsbury, one of only a handful of locations on the UK rail network where semaphore signals are still in use. In the background is the mighty Severn Bridge Junction signal box, the largest operational mechanical signal box in the world.

A fairly recent addition to the signalling at Peterborough is signal P437, it controls the northbound exit to platform 2, mainly for use by East Midlands Train services to Spalding and Lincoln. It's easily distinguishable by the fact it's an LED, rather than standard colour light. Behind it, on platform 3b (ironically!) is EMT dogbox 153311 with the 1511 Peterborough-Lincoln Central. 16 January 2010.
