Hey YT , honestly I have never heard of anyone calling a coach a “triaxle” Is this common these days? A rigid lorry was know as a 6 wheeler so why not call the coach a 6 wheeler or do you bus guys like to be a bit different.
Might well be that we like to be different. But it is commonly known as a tri coach as it obviously has 3 axles. In the tour industry they are very common but obviously at the higher end as they are expensive. Used mainly for long distance work as they hold more passengers and the third axle takes the additional size and weight. Also they are rear wheel steer too because the coaches are a fair amount longer than a standard. Also we have the inter decker coaches which are same size but higher having an upper deck. Similar to a double decker bus but longer and of course goes without saying much posher.
