Is this train thing really different from the average "digital nomad"?

They too are away from their old standing friends, and since they are usually not intending to stay forever in the country they stay in, they're probably not investing in any deep connections there either.

In fact, given the huge loneliness/isolation trends, he is probably not that different to the average stationary person in this regard either.

DN here. It’s definitely different insofar that nomads frequently live in longer term shared spaces (ie weeks to months) and it’s pretty easy to meet people in these situations.
