Train Sim World 6: Canadian National Oakville Subdivision: Hamilton - Oakville

Train Sim World 6: Canadian National Oakville Subdivision: Hamilton – Oakville is a downloadable content (DLC) expansion developed and published by Dovetail Games, released on August 26, 2025. This DLC introduces a 24-mile (41 km) route set in the southern Ontario region of Canada, connecting Hamilton to Oakville. Players can operate freight services along the Oakville Subdivision, experiencing the complexities of managing various industries and rail yards. The route is designed to offer a detailed and immersive simulation of Canadian National's operations in this area.

The DLC features two locomotives: the EMD GP9rm and the EMD GP38-2, both in Canadian National livery. The GP9rm, a rebuilt version of the classic GP9, offers a spacious post-rebuild cab, while the GP38-2 provides versatility for various freight duties. Players can engage in switching operations, managing pickups and drop-offs across multiple industries, and navigating through extensive rail yards. The route's design emphasizes realism, with accurate representations of signals, mileposts, and terrain, capturing the essence of the Oakville Subdivision.

Promotion for the DLC was conducted through Dovetail Games' official channels, including announcements on their website and community forums. The release was highlighted as part of the broader updates to Train Sim World 6, which aimed to enhance the overall gaming experience with new routes and improved features. The DLC's availability on multiple platforms, including PC, PlayStation, and Xbox, broadened its accessibility to a wider audience.

Upon release, the Canadian National Oakville Subdivision: Hamilton – Oakville DLC received mixed feedback from the community. Some players appreciated the detailed representation of the route and the inclusion of both switching and mainline freight services, praising the immersive experience of operating trains in the Oakville Subdivision. However, others felt that the route's relatively short length and limited variety of services did not offer as much depth as other expansions in the series. As of now, the DLC continues to be available for purchase, with its reception varying among players based on individual preferences and expectations.
