Overview I would love to see the existing Cardiff City Network receive a Modernisation Expansion that updates the route to reflect the present-day South Wales Metro. Rather than developing an entirely new route, this expansion would modernise the existing Cardiff City Network with: full overhead electrification (OHLE) across the Core Valley Lines the new Class 398 Citylink Tram-Trains a completely rebuilt modern timetable updated infrastructure where appropriate modern Transport for Wales operations Since the original Cardiff City Network was released, the real railway has undergone one of the largest railway transformation projects in the United Kingdom. The South Wales Metro has fundamentally changed how the network operates, making the existing Train Sim World route an excellent candidate for a modernisation expansion. Why This Expansion Would Be Great for Train Sim World One of the biggest strengths of this proposal is that it builds upon an existing route instead of requiring an entirely new one. The Cardiff City Network already provides the geographical foundation. By modernising the infrastructure, introducing the Class 398 and creating a completely new timetable, the route would feel almost like a brand-new experience. Players would experience: modern electric Metro operations rapid acceleration high-frequency commuter services modern passenger facilities level boarding operations battery-assisted tram-train technology dense Metro-style stopping patterns Rather than simply introducing a new train, this expansion would completely transform how the route is played. Why the Cardiff City Network Should Be Modernised Since Train Sim World's Cardiff City Network was released, the real railway has changed dramatically. The South Wales Metro programme has introduced: electrification of the Core Valley Lines major infrastructure upgrades new stations and modernised facilities Class 398 Citylink Tram-Trains higher service frequencies modern Metro operations To accurately represent today's railway, the Cardiff City Network could be updated with: overhead line equipment (OHLE) across the electrified sections Class 398 tram-trains a completely new 2026/2027 timetable updated AI traffic modern Transport for Wales branding updated stations and infrastructure where appropriate This would transform the Cardiff City Network into a modern railway while continuing to make excellent use of an existing Train Sim World route. Why Now Is The Perfect Time The timing for this expansion could not be better. The Core Valley Lines have now been fully electrified as part of the South Wales Metro programme. The first Class 398 tram-trains are entering passenger service following extensive testing and driver training. This means the Cardiff City Network in Train Sim World now represents an earlier period of the railway's history. A Modernisation Expansion would allow Train Sim World to accurately represent today's South Wales Metro and showcase one of the biggest railway transformations currently taking place in the United Kingdom. Real World Operations The Class 398 is planned to operate on services including: Cardiff Bay Cardiff Queen Street Pontypridd Treherbert Aberdare Merthyr Tydfil These routes now feature: fully electrified infrastructure modern Metro operations higher service frequencies faster acceleration improved accessibility modern passenger facilities The South Wales Metro has transformed these lines into a completely different style of railway compared to when the original Train Sim World route was developed. A Completely New Timetable One of the biggest improvements this expansion could introduce would be a completely rebuilt timetable. Rather than simply replacing existing services, the timetable could reflect today's South Wales Metro by introducing: Class 398 tram-train services higher-frequency Metro operations updated stopping patterns modern electric services greater timetable density updated AI traffic more realistic commuter operations Combined with the installation of overhead wires across the electrified sections, the Cardiff City Network would feel almost like a completely new route while remaining faithful to its real-world transformation. Unique Gameplay Features The Class 398 would introduce gameplay currently unique within Train Sim World. Features include: electric operation battery capability fast Metro-style acceleration modern digital cab high-frequency station stops modern passenger information systems quick turnaround operations excellent visibility from the cab Its rapid acceleration and frequent stopping pattern would create an engaging driving experience where players are constantly interacting with signals, stations, and the timetable. Strong Potential for Future South Wales Metro Content One of the biggest strengths of developing the Class 398 is that it represents the future of rail transport in South Wales. If Transport for Wales content continues to expand in Train Sim World, the Class 398 could naturally be reused on future Metro routes and timetable expansions. Potential future content could include: additional South Wales Metro branches Cardiff Crossrail Cardiff Bay extensions future tram-train infrastructure expanded Metro services This makes the Class 398 a valuable long-term investment rather than a vehicle intended for only one expansion. Why Players Would Enjoy This Expansion This expansion would: modernise one of Train Sim World's existing UK routes reflect today's real-world South Wales Metro introduce an entirely new tram-train driving experience add overhead electrification across the existing route introduce a completely rebuilt modern timetable increase timetable variety introduce modern electric commuter gameplay provide significantly greater replayability lay the foundation for future South Wales Metro content Most importantly, this proposal is not simply about adding another train. It is about bringing an existing Train Sim World route up to present-day standards by recreating one of the most significant railway modernisation projects currently taking place in the United Kingdom. The combination of full electrification, the Class 398 Citylink Tram-Train, and a completely new modern timetable would transform the Cardiff City Network into a fresh, authentic, and highly replayable experience while making excellent use of an existing route. For these reasons, I believe the Cardiff City Network Modernisation Pack would be one of the most realistic, valuable, and exciting expansion opportunities for Train Sim World. Thank you for considering this suggestion.
I'd pay for a loco on this route if it meant getting it expanded to Barry Island, as was originally intended, plus any other route extensions that make sense (I don't know enough about the route to say!). And yes, yet another AI-written suggestion. Thinking that "high-frequency station stops" and "modern passenger information systems" would be "unique within Train Sim World" is just bizarre.
i’m a fan of the idea, but these ai generated suggestions have to stop. it’s lazy and if i was dtg i’d be more persuaded by a suggestion written by an actual human
Sure somebody would see it viable, but I am expecting further Welsh routes down the line centred on Cardiff, theirs Newport to Cardiff which sees GWR running along plus CrossCountry. To expand the network of tocs as forementioned. Cardiff to Bridgend also with GWR. Even if it was a running section thing like WCML has why stop at Bridgend when you could potentially go Swansea. Can't really see Manchester services coming to TSW from Abergavenny line. But maybe someone like Incredible trains could finish off the branches to improve the network albeit quite large, like done on Great Western Route.
Part of the problem is that the AI is scraping other AI suggestions and mimicking them. Hence every suggestion is a 'completely new experience' with 'unique gameplay' (clue: it's not, on either count).
They are among the most ghastly looking trains to appear on the UK rail network, they make the Class 142 and 143 Pacers look like stylish luxury liners!
