Upcoming Release Ecw Remaster And Southern Class 171 & 377/3 - Arriving Tomorrow!

Get ready for a brand new look at a UK classic with the East Coastway Remastered, coming as a free update to all existing owners, and arriving alongside the release of Rivet Games' Southern BR Class 171 & BR 377/3 on Thursday 26th February 2026!



Accompanying the East Coastway Remaster, this add-on includes two trains operated by Southern; the Class 171 (in /7 and /8 versions) and Class 377/3. This was originally announced in our October 2025 Roadmap and more recently with the February 2026 Roadmap, but if you missed it, here's what you can expect from Rivet's newest trains.

The New: Southern Class 171 & 377/3
Timetable & Layers


Along with the 3 included scenarios, there will be 322 playable services included with these trains. Gen 8 players will have the same timetable as Gen 9 and PC players. Tyler from Rivet Games has given us the full timetable breakdown on what you can expect from the December 2017 - May 2018 setting.

Experience a new timetable built from scratch using the December 2017 - May 2018 Working Timetable. In the Add-on, you will find two identical versions included: one where the Seaford and Lewes services are operated by the Class 377/3 and the other operated by the Class 313.



Services:

• 322 playable included.
• 376 playable with all layers.
• 1,008 including AI services, with all layers.

Compatible Layers:

• Railhead Treatment Train
• Brighton Main Line
• Thameslink Class 700
• Southeastern High Speed
• Class 20
• Class 86/2 (coaches only)
• Tees Valley Line
• ROG Class 37
• Flying Scotsman
• Class 33
• Riviera Line (Class 150 AI)

Southern BR Class 171


The Class 171 is a variant of the Class 170 operated by Southern. The primary difference is the fitting of a Dellner coupler, rather than the usual BSI coupler, for emergency coupling to Southern's EMU fleet. Southern has shuffled around their 171s a bit, but since the timetable is set in 2017-2018, we are including the two-car 171/7 and the four-car 171/8 exclusively as part of this Add-on. Rivet have also made audio improvements which will be backported to Birmingham Cross City and Fife Circle Class 170s.



The Class 171 operates diesel services over the Marshlink line between Ore and Ashford International, connecting to Brighton. These stop only at Polegate and Lewes, except for the first service of the day which makes additional stops between Lewes and Brighton.

BR Class 377/3


Class 377/3 units were originally built as Class 375/3s for Connex South Eastern (later Southeastern), but 28 of them were transferred to Southern. Their designation was changed when they were transferred to reflect the fitting of DOO equipment, and their change to Dellner couplers (although the 375s would eventually get Dellners as well). They are formed of three carriages and are third-rail only.



The main difference between the 377/3 and the 377s already in TSW are the older headlight clusters, the interior, which is 2+2 seating throughout with First Class only on one end, and the number of cars is three instead of four. This change in formation also has the knock-on effect of performance feeling a little different, with one less motor coach than before.

Following community feedback during our earlier previews, our teams have made updates to the audio on the Class 377/3 to ensure this is accurate, and these will be available in a post-release update to the Add-on. We'll communicate when these changes are available via our community spaces and social channels.

Known Issues for ECW Remastered
We wanted to let you know of a few issues ahead of the release of the East Coastway Remastered route that we weren't able to fix ahead of launch, and will be arriving in our next core update.

• Berwick station announcements are too quiet
• You may notice a "NO Name: ECWTFCL37704carL" in the train spawn list for the 'Class 377/4 SN'.
• The prompt to switch to 'Immersion' mode during the introductions doesn't appear
• Class 66 locomotive loads in its default livery in the 'Livery Designer' menu

Please let us known more feedback on the route, with any issues you've spotted, or areas you enjoy, on our Forum Feedback Threads, or in the official Dovetail Discord.

 

Not something we were tracking/did intentionally and I think, judging by the other thread, we'd have had more complaints if we'd delayed it.
