Passenger Assist allows you to request an assistance booking in advance. Any train company can organise assistance for your entire journey, even if you are travelling on multiple services. In addition to receiving support getting on and off the train and around the station, Passenger Assist can help with luggage too. You can find more details about Passenger Assist and contact details for each train operator here.
Assistant dogs are welcome on the train under the Assistance Dogs Travel Scheme, supported by Assistance Dogs UK. You can find more infomation and advice on travelling with animals here.
