Train Sim World 6: Transport for Wales BR Class 142 Pacer DMU

The Transport for Wales BR Class 142 Pacer DMU Add-On for Train Sim World 6 was developed by Just Trains and published by Dovetail Games. It was released on 25 November 2025, and is provided as downloadable content requiring ownership of the base Train Sim World 6 game.

This DLC adds the iconic British Rail Class 142 “Pacer” DMU, as operated under Transport for Wales, to the simulator. The model comes in period‑accurate teal‑toned liveries reflecting its final years in service with TfW, including both a generic unbranded variant and one bearing a promotional “The start of a new journey” banner. The add-on features a modernised exterior (with LED headlights, updated doors, sanding equipment and antenna), an updated passenger interior with period‑correct seating and bilingual signage, and a fully detailed driver’s cab with operational systems like GSM‑R radio, DRA and TPWS.

Gameplay with the Pacer is designed around the Cardiff City Network: Radyr & Coryton – Penarth & Bae Caerdydd Route Add-On; the DLC includes a 2019‑era timetable with hundreds of services across the network, a selection of scenarios (including a railtour with a headboard variation), and support for custom content tools like Livery Designer, Formation Designer and Scenario Planner — allowing players to build and share their own content or relive peak‑era Welsh commuter operations.

Promotion for the DLC began with official announcements in the 2025 roadmap, followed by developer previews highlighting the updated Pacer model, its modernised features, and the new 2019 timetable. Early community response has been generally positive: fans of UK regional rail recognise the Pacer’s unique character and often describe the modelling and suspension physics as faithful to the “bouncy” feel of the real thing. Given the long‑running affection (and occasional criticism) for the Pacers in real‑world rail history, reception among the Train Sim World 6 community seems to appreciate the authenticity and nostalgic appeal this add‑on delivers.
