The one train working on that branch is enforced by use of a train staff.

They're contact boxes containing an electrical contact to prove the position of the semaphore arm. On Southern semaphore signals, they're usually positioned at the same height as the arm spindle. I presume the second contact box on the second signal is used to extinguish the approach light when...

Could it mean 'Frodingham Depot'?

Garelochhead station only has an uphill slope on its east side, so the train in the photo would have to be facing north. The shadow suggests the presence of a gate at the start of a fenced exit path going off to the left (i.e. north), but at Garelochhead the path runs south from the gate.

I don't think it's Ardlui; I think it's Arrochar & Tarbet. Both stations are approached by subway and the slopes are similar, but the small building that's just visible on the left edge of the photo is only present in that position at Arrochar. We have an explanation for the train being in the...

The shadow on the left suggests that it's one of the stations where the island platform is approached by a subway rather than a footbridge. See for example the image of Ardlui station here. I think it's Arrochar & Tarbet station. The edge of a small building is just visible on the left edge of...

"Finneston" should be "Finnieston".

Like this, for example?

Cameron Bridge.

Proceeding in place of preceding. Formally in place of formerly.

"Up to" is frequently misused as though it means "approximately". For example, you may read "up to ten thousand people will be affected" when the intended meaning is "approximately ten thousand people will be affected". The first version literally means "we can't tell you how many people will...

It's in use on the Skipton - Rylstone line.

Dunragit, I presume? A trainman operated barrier crossing may be an appropriate solution, or perhaps an AFBCL, assuming that full barriers are deemed to be necessary. ABCL if full barriers are not required. A CCTV or MCB-OD crossing need not be closed as soon as a train enters the section if...

Comma splice! :smile: I often see prefixes detached from words and their spelling altered to make a legitimate word, but one that doesn't quite fit. In this alternative world, objects are miss placed, people are often miss guided, and Romesh Ranganathan presents a TV show about his miss...

The distance between the two OSS loops is what determines the set speed. Since the TPWS timer on board trains runs for a fixed duration (0.974 seconds for passenger trains and 1.218 seconds for freight trains), you can calculate the set speed (for both passenger and freight) of any OSS if you...

I don't have a public link for that, sorry.

Occasionally I see somebody remark "You learn something new everyday", and it makes me want to reply with "Maybe one day you'll learn how to use compound words correctly." :lol:

That's just part of a wider trend where an alarming number of people seem to be arbitrarily applying a rule that says "a word with fewer than three letters should be combined with the word that follows it", resulting in such nonsense as "alot", "aswell", "atleast", "infact", "infront" and...

Yes; Network Rail Technical Instruction TI 025 "TPWS Loop Positioning - Buffer Stops", dated February 2006.

No, I wouldn't want you to test them either :smile:. If you were really curious, you could roughly measure the distance between the two loops from the platform edge. 4.5 metres gives a set speed of 10 mph, and 5.5 metres gives a set speed of 12.5 mph.
