Do normal people travel by train?

I have a question, do normal people travel by train? It may seem like an odd question but every day Robbie tells me about his fellow passengers or the train crew he meets. I am not sure if Robbie acts as a bit of a magnet to people who are a bit 'out of the ordinary' or if he only tells me about their strange interests. Yesterday he told be about someone he met who was a bus spotter (as well as a train spotter) that wouldn't be so bad if he he didn't give me a verbatim account of his entire conversation. On weekdays we only have a few hours together in the evening, does he really think I want to spend that time listening to a load of drivel about the various types of buses in use in different towns? He chattered on happily as my eyes glazed over (a dangerous thing when driving!) and I wondered why just occasionally he couldn't meet someone ordinary and talk about something a little more interesting than trains, buses, roadworks etc!
