Well there you have it, it sounds like training to be a train driver would be the way to go under normal circumstances. But obviously with social distancing and limited travel the next few years, people might choose to drive private cars instead of get a season rail pass. So I don't think there will be many train driving jobs going.
Starting a business is an option, but what?!
Again, I think my hairdressing business option from many posts ago is viable.
I also have many colleagues who retired as pilots and became driving instructors and are very happy with their lot.
