The main reason would be insufficient demand. Basel-Lugano(-Milano) doesn't have the passenger numbers that warrant two trains per hour.

A second reason would be capacity. Only two fast passenger trains can run through the Gotthard base tunnel per hour and direction because they eat a lot of capacity for slower goods trains. Add to this one hourly train over the Gotthard, which totals a southbound capacity of three trains per hour (with possibility for changeovers in Arth-Goldau). Now if two trains already come from Zurich, there is only capacity for one more through-train from Basel. Any extra train would have to end in Arth-Goldau.

There are additional capacity problems around Lucerne - Lucerne is a terminus station that handles 18 arrivals and 18 departures per hour over only two (!) tracks. According to SBB, no trains can be added there.

I'm not necessarily saying that starting the Milano trains half an hour later is wrong. But it definitely has drawbacks and it would be a lot better if 2h40 from Zurich to Milano could be achieved as originally promised. With that time, no such tradeoffs would have to be made.

A realistic service pattern for the future would be an hourly train Milano-Lugano-Arth Goldau, then alternating two-hourly to Zürich and to Lucerne-Basel, plus an hourly Lugano-Zürich (that may continue to Basel or Shaffhausen, or be also that an alternate Lugano-Zürich/Lucerne-Basel).

About the origin/destination of traffic: EC CIS from Arth Goldau to Como and Milano on spring and summer weekends are well loaded, and quite often fully booked. Considering that Zürich-Bellinzona/Locarno/Lugano passenegr take other trains, I Highly doubt these people only go from Zürich to Milan or viceversa...

2040 or 2050 is a more realistic date, if that line will ever be built.

I don't think so, the plans are as follows:



From Geneva to Lausanne:

First purple stretch are the new crossing points in Mies and Chambésy for the RER Genève that will allow frequencies of 15min instead of the current 30min (this line uses a single track between Geneva and Coppet out of the three on this stretch, so trains need to cross).

The yellow stretch between Coppet and Nyon is a track in Founex to be able to advance freight trains.

Then the blue line is the 3rd and 4th tracks between Gland and Rolle.

Between Allaman and Renens there's going to be a third track and between Renens and Lausanne a fourth track including a new flyover.

The calendar for those projects is as follows:



T: Works
S: In service

So no 4th track all the way from Lausanne to Geneva.

IMHO if there was enough money (and there's not, so it's just a wish of mine) it'd be best to build a second two-track line between Lausanne and Geneva avoiding the current cities which could be used by non-stop services between both cities and beyond (IC, IR, international trains such as TGV's); it wouldn't just increase capacity and offer better speeds since those trains wouldn't mix with local services, it would also reduce noise troubles for freight trains.

The Pilatus Railway is the world's steepest cogwheel railway with a grade of up to 48 %. The railcars are built in 1937 and are thanks to good maintenance in excellent condition. Trackbed and rails are from the opening year of the railway in 1889!

The line is 4.27 km long and runs from Alpnachstad at 437 m to Pilatus Kulm at 2066 m above sealevel, a vertical distance of 1629 m. So the average incline is 38.15 % or 381.5 metres per km. The steepest grade is 48 %.

SBB Cargo has removed the Ae 6/6 from regular freight services after 61 years of service. These 6 axle locomotives were built by SLM, BBC and MFO from 1952 until 1966, 120 in total. Together with the Re 4/4 I they were the 1st modern electric locomotives for the SBB with regular bogies. Originally they were used on the Gotthard line to pull heavy freight and fast trains. After they where replaced on the mountain lines by the Re 6/6 / Re 4/4 combinations they where used mostly for lighter freight on all other lines. And their use is not completely over, 10 will be kept in reserve for this years Sugar Beet campaign later this year. And several are already in use for SBB Historic and other organizations that will keep this historical locs running for years to come.

A small image dedication for this legendary locomotive.

No, it's for regional, national and international trains.

AB-RhW Bergbahn Rheineck-Walzenhausen, 1200 mm, 650 V DC, Riggenbach and Strub rack, the only "conventional" 1200 mm gauge railway in the world I am aware of (there are a lot of funiculars of that gauge, and a railway in Genova, but all of them use Abt switches - in other words, without mobile parts and with vehicles with double flanged wheels on one side and flat wheels on the other side). This railway has just one switch leading to the depot and only one EMU shown in the photo.

AB-RHB Rorschach-Heiden Bergbahn, 1435 mm, 15 kV 16,7 Hz, Riggenbach. Trains on this line continue beyond the rack section owned by Appenzeller Bahnen on SBB tracks.

It's for a cogwheel, extra traction on the steep track.

Well that's what I would have thought, but he said it's a conventional railway!

I meant that the RhW is the only existing railway with a track gauge of 1200 mm, with the exception of a certain number of funiculars and the Principe-Granarolo rack railway in Genova. The point is that this rack railway uses quite normal tramways/EMUs, but the line has only two switches in the crossing loop, but these are built similarly to the Abt switches of funiculars:



This means that on the Principe-Granarolo there is a vehicle that can run on the left track in the photo but not in the right one, and viceversa the other vehicle can only run on the right track. The left vehicle has double flanged wheels on the left side, and flat wheels on the right side. This means that the RhW EMU in my photo is probably the only rail vehicle built to the 1200 mm gauge.
