Venue - Avanti West Coast train line

In Avanti West Coast trains not only do I feel calm myself, but it seems that the design also affects the mood of other customers. I have never been on an Avanti West Coast train in which passengers were shouting or talking loudly on phones, which constantly happens in other trainlines. Even babies seem calm on Avant West Coast trains! People don't look frantic throwing stuff everywhere, putting their feet on seats etc. Also, the staff who work on these trains are always calm. I often use Avant West Coast to travel from Scotland to England. I so much enjoy reading and working, which I can never do on any other train lines. I don’t reach my destination completely drained, irritated and in bad mood, which happens almost every time when I have to use other train lines. I live in fear that one day Avanti West Coast will replace these trains with different ones without having realised that there is something really successful in the current design. This must be researched so that the same principles can be used in the future to design new trains. I am not saying that Avant West Coast must pay for this research. Maybe an organisation that supports autistic people could do this and the outcome of this research could be useful to any train line.
