There are many reasons why the Journey you requested cannot be found. The two most common reasons are:
- There are no trains on the route you have requested within 2 hours of the time you have requested. To reduce load on the system, the timetable search engine only searches within 2 hours of the requested time. So entering a late night or early morning time may not find any trains. In this case try a later or earlier time as appropriate.
- The route you requested (particularly if you specified a "via" station) may not be a valid 'ticketable' route. To overcome this break the route into sections. See "How does the site work out the routes I can take?" below.
