Line reopened with EC164 heading in right direction towards Graz, about 75 mins down

My interpretation is a fatality in the line, line blocked for an unknown duration

EC163 with 11197+11157 turning round at Lachen (SZ) and heading back to Zürich

What does a TK involve?

I don't know exactly. But the abbreviation stays for "Technische Kontrolle" while an R1 is a "Revision". This means that components are only controlled (if they will do for another year) instead of overhauled.

18505 is no longer part of the SBB-H collection. On July 13.07.2022 it was sold to OeBB who reportedly intend to use it on trains connected with the rebuilding of the Gotthard road tunnel

4029 has been delivered to Zürich

4026 is being used for test purposes at Alstom Bautzen

4027 4028 4030 are near completion in Vienna

For the record:

"For me, “dual gauge” and “metre gauge” are compound adjectives here and thus require hyphens. I would put your sentence as follows:..."

Definitely agreed! And the distinction here is not between "twin-gauge" and "dual-gauge": it's between "track" and "station", I suggest. A dual-gauge station might or might not have dual-gauge tracks as opposed to separate single-gauge platforms / tracks.

And I should know: my mum grew up in Gladstone, South Australia, a place which pretty much only exists because three gauges used to meet there!

Dual gauge track means that trains of two different gauges can run over 
that section. It does not matter whether there are 3 rails (as in Chur - 
Domat-Ems) or 4 rails (as at a gauge-changing facility). The term still 
applies if, on a 3-rail section, the "common" rail changes from one side 
to the other (look at the Tillig catalogue for what this looks like).

Luzern - Horw is three-rail in the first part and four-rail in the second. In Kriens Mattenhof there is a change-over from three-rail to four-rail!

https://m.youtube.com/watch?v=MieslGEL2to Looks like fully bi-directional. Cheers, Ewan

> Chur - Domat/Ems is a line with double track with one dual gauge track and one metre gauge track

Same as Luzern - Horw, right?

> Chur - Domat/Ems is a line with double track with one dual gauge track and one metre gauge track

Are both lines bi-directional, or is the standard gauge bi-directional and the metre gauge tracks only signalled in one direction? Or is the dual gauge line bi-directional and the metre gauge line one way only?

Yes, Zweisimmen has been mentioned.

Gauge-changing facilities are a specific case, although the term dual gauge still applies.

Dual gauge track means that trains of two different gauges can run over that section. It does not matter whether there are 3 rails (as in Chur - Domat-Ems) or 4 rails (as at a gauge-changing facility).

I do not believe that the term "twin gauge" is correct usage.

Concerning Chur-Domat/Ems

Isn't there, or wasn't there until quite recently something similar on part of the RBS system?

Has anyone mentioned Zweisimmen? Both twin gauge and dual gauge transfer tracks.

Chur - Domat/Ems is a line with double track with one dual gauge track and one metre gauge track
correct? :-)

I’m pretty sure that nobody could improve on that….

Line = a route between two points, e.g. Chur-Ems Werk a line that is laid with dual-gauge track.

Chur - Domat/Ems is a line with double track with one dual gauge track and one metre gauge track
correct? :-)

Furthermore, when does a station become a separate entity? For example is Brig Bahnhofplatz MGB really part of Brig station?

There are different answers to this question:

• While "Brig" and "Brig Bahnhofplatz" are distinguished in the timetable, a departure of the Appenzellerbahnen in St. Gallen will appear as "St. Gallen", track 11 or 12. Same for Bern (RBS), Visp (MGB), Chur (RhB) or Langenthal (ASm). Thus, mostly the different gauges don't make a separate entry.
• For timetableing several stops can be taken together. The problem of the SBB app is, that it always thinks that I choose a distinctive stop. Searching a connection from "Brig" to "Fiesch" shows as first point a 7 min walk, which would be correct, if I'm arriving from Goppenstein, but not, if I start from Brig.
• Bus and tram stops are always separated, e.g. "Brig, Bahnhofplatz", "Bern, Bahnhof" etc.
• From an operational point of view, the parts with different gauge are always separate. You can see them on the official maps as small blue squares, e.g. "Visp MGB-bvz". If you click the details you can see that they are always classified as " Zugeordneter Betriebspunkt" (assigned operational point or something like that...)
