This is an old photo, from when I visited Zurich in 2015. The Swiss rail network (SBB – Swiss Federal Railways) had installed a Starbucks outlet on this train in 2013 in a bid to encourage people to use public transport. The branding doesn’t seem to have lasted long and there’s little mention of this on-line after 2015, so I assume that it was discontinued.
But this does remind me of my idea to put a Greggs carriage on every train, or at least every intercity train to begin with. No point in getting too ambitious straightaway….
