Public transport users in Great Britain can now use Google Maps to plan an entire journey from any two points on the British mainland, including journey duration and transfer times.

While Google Maps has featured a “public transport” option for some time, coverage had been patchy, with travellers in Wales, the North of England, and the Midlands left unable to calculate their routes using the service.

However, the company has now incorporated data from Traveline, a public transport information service set up by local authorities and transport operators in 2000, to provide coast-to-coast coverage.

Additionally, if you have selected “public transport” but walking is quicker, Google Maps will display the walking instructions first, with public transport options coming second or third.

PC Pro’s test of the service reveals you can get from Newcastle University to Aberdaron in rural northwest Wales in only 15 hours and 45 minutes, should you wish to, or John o’Groats to Dungeness in about a day.

As well as bus, train and tram infrastructure, boats have also been included. If you are looking to nip across the Solent to the Isle of Wight, you can easily find out how long it will take by ferry or hovercraft.

However, if you are looking to go a little further offshore Google Maps can still be a bit more hit and miss. Apparently it is possible to travel from Portsmouth to Callanish in the Outer Hebrides using public transport, but you can’t come back again.
