A liquid addition system for mounting on rail vehicles, comprising a liquid outlet 1006 configured to direct liquid towards a rail 112 in use, a pump, and a liquid conduit in fluid communication with the pump and the outlet. The conduit defining a first, open area for free passage of liquid, and a second area constructed from a deformable foam adjacent the first open area. A liquid addition system with a pulsation device to confer oscillatory pressure within the liquid. A liquid addition system where the fluid has a liquid component and a gaseous component (bubbles). A liquid addition system comprising an electric field generator configured to create a potential difference between the fluid outlet and a rail A wheel slide protection system comprising a controller and a wheel slide sensing system. A railway management system comprising a plurality of rail vehicles comprising rail treatment systems and a controller configured to receive data indicative of the location of low rail-wheel friction locations and send instructions to at least one rail vehicle to treat that section of. A method of managing a railway comprising a plurality of rail vehicles comprising with wheel slide protection systems.
