The problem with hydrogen is that it's such a low density fuel compared to diesel that you'd need a dedicated tank car to replace the fuel tank on each locomotive.

Having said that, if you built a solar farm that powered an electrolysis plant that pumped the hydrogen only as far as an adjacent rail terminal, you COULD have something there. Fuel cells really don't work for cars, for a number of reasons - but where you have fixed routes and regular schedules? There, you can overcome the challenges that make hydrogen cars impractical.

However, the process used in order to make that electricity to power those trains is burning fossil fuels. If these plants which make electricity were to use solar or hydrogen-powered energy to make this electricity, then these trains and their sources of energy would be completely zero-emission.
