Train Sim World 6: BR Heavy Freight Pack

Train Sim World 6: BR Heavy Freight Pack Loco Add-On is a downloadable content (DLC) expansion developed and published by Dovetail Games. Released on August 26, 2025, this DLC brings two iconic British diesel-electric locomotives—the BR Class 40 and BR Class 08—into the game, enhancing the Northern Trans-Pennine route with authentic heavy freight operations. The BR Class 40, known for its distinctive "Whistler" nickname, was one of the first mass-produced diesel-electric locomotives for British Railways. The BR Class 08, affectionately called the "Gronk," is one of the most common sights on the British railway network, particularly in shunting and yard operations. This DLC is compatible with Train Sim World 6 on PC, PlayStation, and Xbox platforms.

The BR Heavy Freight Pack offers players the opportunity to operate these historic locomotives on the challenging Trans-Pennine grades. The BR Class 40 is featured in its British Rail Blue livery, while the BR Class 08 is presented in its original BR Green livery. The DLC includes various freight wagons, such as oil tankers and coal hoppers, allowing players to engage in realistic heavy freight operations. Additionally, the pack introduces new scenarios and services, providing a comprehensive experience of British freight haulage during the diesel era.

Marketing materials showcased the BR Class 40 and BR Class 08 in action, illustrating their capabilities and the dynamic freight services players would encounter. The DLC was positioned as an essential addition for enthusiasts of British railways and those seeking a more specialized experience within the Train Sim World 6 universe.
