Whilst I agree that parking bikes on the Chunnel in a herring bone to the right, when facing the direction of travel, would make more sense. I do wonder how many bikes (given the reasonably large number carried) actually ever fall over when parked to the left? I’d wager that the number is very low.
Over the 25 years plus of carrying bikes on the Chunnel, the operator of the service has sort of evolved. In the early days it was sometimes just one or two bikes per train, each bike held in a cradle. Then it was on the centre stand, until the operator realised that not all bikes have a centre stand and of those that do, some owners are incapable of lifting their bike onto it and / or getting it off again, without rupturing themselves and crying. One oddity of the “Use the centre stand!” barked out order, was the guards’ insistence that the bike be in gear; a pointless operation when the rear wheel is off the ground. I shan’t even go into the previous fear that touching or even looking at the silvered access channel that runs down the centre of each carriage was sure, in the operator’s eyes (and in the eyes of some bikermates) to result in instant death. That fear has receded with time and experience.
The truth is, as with the ferry, a motorbike is a pain in the arse for the operator to transport, as it only has two wheels. The same pain in the arse can manifest itself when the owner of the bike struggles to lift the bike off its side stand….. which brings us neatly back to the topic of the opening post and the thread. That bikes are also a pain in the arse to pick up when they are lying on their side, is a gimme. That the skilled motorbike owner is sometimes cursed to find themselves in the same carriage as a bunch of numpty bikermates to endure, is of course, just the lottery of life.
