Southern Class 171 & Class 377/3 Add-on

Including two trains operated by Southern; the Class 171 (in /7 and /8 versions) and Class 377/3, and a new timetable for the East Coastway route, coming from Rivet Games!



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.

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.

East Coastway Remastered - Important Xbox Notice
This morning, we've been informed overnight by Microsoft that there were some outages in their submissions system overnight, and the update for East Coastway (adding all the Remastered content) will not launch at 10am GMT (alongside the Southern BR Class 171 & BR Class 377/3 Add-On).

This will affect Xbox and Xbox on PC only. All other platforms will release at the expected times.

Whilst the remastered update is recommended for the intended experience, the Class 171 & Class 377/3 add-on will still be operable on the original East Coastway add-on until the patch is released - but some gameplay elements may not function or work at the expected quality until then.

We don't have a confirmed release time as of yet, but we will keep you updated! Apologies for the inconvenience.
