Switzerland's Montreaux-Oberland Bahn is to introduce Gauge-changing Trains on its metre-gauge Golden Pass route which will be able to continue on standard gauge tracks to Interlaken. A though service will be more attractive to tourists than one that has a break-of-gauge.
Also rolling stock utilisation will be improved, as rolling stock will not be force to wait doing nothing at the break of gauge. There would be 4 through GCT per day, which would indicate that GCT are more effective that broadening the metre gauge lines.
58 variable gauge bogies are under construction for new and existing rolling, by Alstom, for SFr13m.
The article in the August 2016 edition of Railway Gazette International, p72, does not mention if the Swiss GCT is suitable for other countries, such as Australia, nor does it say that the GCT concept is suitable for freight rolling stock. What is the maximum speed of the GCT?
