Seems like a tradeoff. You don't have to build any wires, which some find ugly. Mind you, a railway isn't generally an area any find beautiful. But you do have to refuel, come up with a new fueling system, the time tradeoffs of this, probably lose some acceleration profiles (slower ride overall), and you have to accommodate the fuel and the means of converting it to energy on the train, which is almost certainly larger and louder than an electrical catenary-driven motor, which often also lets you have each car be self-propelling, rather than a singular engine propelling the whole load (again, this give electrical the edge over hydrogen). The biggest advantage is that politically, it gives you cover for not doing anything for even more years.
