I'm wondering whether the word you've put as '[unclear]' might be 'through' (in the sense of 'as a result of')?
Agree (though "Eastern Switzerland" is an odd phrase re a train that has come via the Simplon route.
On your note 5, would this have been the
Petite ceinture?
Definitely, the GC would have taken too long for the return times (very smart working even so).
Unclear word = ‘trams’ or ‘trains’ ?
I would go for "trains" though I suppose a British visitor might have called the electric railcars "trams."
Some interesting features of the trip:
Steam from Dijon to Vallorbe.
The route from Vevey to Gruyeres (no doubt the shortest) - CEV (CF Electriques Veveysans) via Blonay and the long-closed line to Chatel-St-Denis, then the Gruyeres-Fribourg-Morat system via Bulle to Gruyeres.
Britannia 70014 on the boat train had presumably worked the Down Golden Arrow that morning, leaving 70004 for the evening return train.
Could this have been a draft of an item that was submitted to one of the societies, such as the LCGB?
Possibly. Anyone got their magazine, or the (RCTS) Railway Observer for late 1951? I wonder if those societies might be interested in the document?
