One-off trips require learning a new mode of transport, so one-off are a natural weak spot of a "new" mode of transport. (how much time buffer do I need at the station, how do I conveniently pay for my ticket and so on). Getting people to switch rarely happens. Your best bet, as a new rail line are people whose regular transportation demands change while the line is still new and shiny (e.g. new job at the far end of the line, do I drive/move/rail?). This also meshes very well with the real estate development model of financing the line.
