Swiss - A number of funicular's including one over 4km long to Montana. Only the Swiss would have Funicular's running as commuter services. Every 20-30min or so.
Geneva to Paris, via Lyon on TGV - Previously we did the reverse journey. Most would think TGV wow it will be fast. Well the first 1hr from Geneva to Lyon is up there with a journey over the Blue Mountains, Sydney to Wollongong and Central Coast . The speeds into the corners is often so hard that its hard to stand up and drinks and food move around on the table. This single track is the opposite to a HSR. From Lyon its all 300km/h to Paris.
Paris Metro and RER - 2nd time to Paris. As usual the trains on all lines are frequent, but often smelly either the train or the station. I do like the fact that almost anywhere in Paris is a train station if not 5min walk at worst. Our nearby RER station St Michel is the opposite of DAA, with stairs and a large step up to the train. Overall in Paris if you are in a wheel chair, you don't use the Metro or RER except for a very limited number of stations. And yes some of the trains we used were automated and we survived.
Paris Gard De Nord to London St Pancreas - 2hr to line up and join the train over 1hr late. In that time our seat was changed 3 times and still conflicted with others on the train in our seat when we got there. Yes we had pre-booked tickets along with everyone else. I worked out it would have been quicker to fly and would not have been standing around so long. On board, Eurostar did not impress me. Seats and leg room is uncomfortable, Food on board was crap and slow service. The train was not clean especially the buffet car and there was 4 staff in the buffet but only 1 maybe 2 working. Yes the train got us there quickly, but that was all. I'd use it again because its the right thing to do, not because of the standard of train and service.
London Metro, we stayed near Parson's Green station, which is a nice area 4 stops short of Wimbledon on district line and the trains, station and users on this line reflect this. The District line takes you to most of the usual tourist destinations ie Big Ben, London eye etc. The London Metro did impress me with its frequency of service, some stations you barely have time to get off and the next train is there. The trains are clean, no graffiti, you are informed on everything, even a 30sec delay and they tell you why. Train infront has Red light etc etc. On District line near Parson's Green is Earl's Court which is a complicated junction of two branches on each side of District line, This station has a train every 1-2min, many crossing paths as only on one side is there a fly over for some services. The thing is when you are running trains so frequently no one notices if you are held up 1-2min.
The District line has the twin ground power supply, external and internal rail to provide a positive and negative potential which combined provide a larger potential for the train than normally capable by a single 3rd rail. Looks complicated and expensive.
Euston to Midlands - We caught a train to Penkridge, which you catch a train to Stanford Junction, then back one towards Birmingham. Now to book direct, cost 180punds, but to book to Stanford is 80 Pounds on the Midlands, not Virgin EMU train. Which was nice basic, includes very good wifi. Leaving Euston it wasn't long before we were travelling at plus 140km/hr and held this most of the way. Then at Stanford the Penkridge train was waiting across the platform. I asked the guard if I could buy a ticket on the train, no problem, he never came as its only 6min down the line. So got a free bee. Penkridge is interesting as it was supposed to be closed in days gone by. Virgin runs trains through it at nearly 200km/h. Again this service had high performance wifi. Trains were mostly clean and graffiti free.
Penkridge to Birmingham airport. Pretty much same train as above, quick run to Birmingham, then change on same platform and on to airport station. Again excellent wifi and helpful staff.
One downside to the Midlands EMU's, alot of people travel with luggage, but there is no where to put it apart from doors. They need to remove a row of seats on one side and install racks. The longer distance services are 2+2 across with arm rest and shorter 2+3 with no arm rest.
