Offsets are one of the key parts of reporting accurate arrival and departure times across the rail network. Network Rail collect their own set for the industry as part of ‘The Margin Book’ which gets incorporated into SMART. Realtime Trains collects its own. This blog post is about the processes and more about the mechanisms that are followed.

This coming timetable change in December marks the biggest change to the Great Western Main Line in decades. LNER are also continuing to introduce their Class 800 and 801 ‘Azuma’ fleet. This is how Realtime Trains prepares for these changes.

Every now and again, we’ll make posts covering what’s changed since last time we covered RTT. There’ve been numerous minor updates since the launch nine days ago and this post covers all of them. We’ll be selling RTT pin badges from tomorrow, more information at the bottom.

Realtime Trains has received its first major upgrade since August 2013 - we’ve recoded major parts of the site and infrastructure and also redecorated while we’ve been at it.

Back in May, we spent our third year providing realtime information at Swanage Railway’s annual Diesel Gala and Beer Festival event. This makes use of the Realtime Preserved Trains technology that has been in development for about 6 years.
