In general, and not pointing in any particular direction, I am a little concerned at the tone of one or two comments recently.
Some questions are best left unanswered, and some unasked.
Please be mindful to show a tad more tact, diplomacy and optimism towards both our new hosts and our previous one. It must be a tricky situation all round, and assumptions should not be made.
An aside, re the Walschaerts valve-gear, when my ex and I lived in the Swiss Federation, four years were in the village of Blonay (a home to Paul Hindemith, who I am reliably informed had a magnificent train set in his attic; we also were on the cooking rota for train crews at the Blonay - Chamby Musee de Chemin de Fer).
