Thanks -- posting-or-not, can sometimes be quirky !
I like stuff about rail gauges -- so here's a question thereon...
Various past "happenstances" have caused s few railways to adopt gauges which are "nearly metre gauge, but not quite" -- both "over", and "under". Two such, arose in different respective areas within a just-over-2000-mile radius of Britain -- differing from each other by a mere 5 millimetres; but in the highly-precise railwaying world, this distinction is enough to matter. On one of these two scenes, nowadays the gauge just clings to life by a thread as regards being in active service; on the other, an appreciable though not huge amount is still in traffic.
Please identify the two gauges, and the areas of the world in which they obtain.
I'm guessing one of these is the Hedjaz railway (1050mm) in Jordan / Syria (and formerly Saudi Arabia), but I have no idea about the other one
Definitely only 5mm, not 50mm?
I ask as I can't think of a guage only 5mm different to metre guage, but at 50mm narrower than metre there would be the "Italian" metre guage of 950mm, measured as one metre between the centre rather than inside of the rails.
Sofia trams 1008mm
Correct -- the Hedjaz system is indeed one of the two.
I was perhaps a bit imprecise: the two gauges are 5mm (truly) different from each other -- they are both "close to metre but not metre", but differ from each other by that tiny amount.
The outfit which is not the Hedjaz, is in and peculiar to a country which seems to get unfairly overlooked in railway lore -- it has abundant and interesting railways, dating from "way back". Hint -- this country's standard gauge, used to have Garratts of a very unusual kind.
Algeria, is right. A considerable part of the system -- lines intended to open up rather inhospitable areas inland from the coastal strip -- was built to the 1055mm gauge: per Wiki, there are 1085 km. running today, on that gauge.
The Garratts "per hint", were the visually magnificent "double-Pacific" express passenger ones built in the late 1930s / early 40s -- unfortunately too delicately and refinedly engineered, to last very long. The 1055mm gauge also had some, more workmanlike, Garratts.
Sheikh martinsh and hexagon789 Bey: "you each got one". Would you like to negotiate, re which of you takes the floor?
Correct !All have been used on coins.
Thank you
For what feature is the South Durham & Lancashire Union Railway best remembered?
A clue - the connection is a station (now sadly closed), not far from where I live in the Meon Valley.
I'm a bit new to this but I'll have a go to get things moving again...
In what year was Goole Signal Box built, and by which company?
