In Hanshin(Osaka-Kobe) area, it is often said that inhabitants along Hanshin Line are poorer folks, inhabitants along JR Kobe Line are ordinary folks, inhabitants along Hankyu Line are richer folks.
But, I think the trend is no longer applied to these days' Osaka-Kobe area.
I heard MTR in Hong Kong also has railway lines influenced by passengers' character: East Rail Line and Island Line.
Since East Rail Line terminates at Lok Ma Chau or Lo Wu, which is immigration to China, many Mainland Chinese ride on East Rail Line. They often have some quarrels with Hong Kongers in trains.
Not only quarrels but also drug abuse is found in trains. According to my follower, he found empty medicine bottles in a train on East Rail Line.
On the other hand, Island Line has polite passengers. I think this is because towns along the line are most prosperous areas in Hong Kong. For example, Causeway Bay's average rental fee of tenants is said to be world's second highest price.
Observing passengers' character may be interesting.
