RO-Scale BNSF Sunflower sub is a game available on the Roblox platform. Developed by American RO-Scale studios, this game allows players to drive BNSF trains along a fictional line. The game features two fictional mainlines, namely the Sunflower sub and the Bluewater sub.

With a focus on simplicity, the game has three rules that players must abide by: no harassment of others, no stealing of other players' trains, and a limit of 50 cars per train. Players are also advised to couple at less than 15% to ensure smooth gameplay.

While the game offers a realistic train driving experience, it is important to note that the use of the bell toggles flashing ditchlights. BNSF units do not have ditchlights in real life, so it is recommended to avoid using the bell.

The developer has plans to revamp the scenery, add new trains, and make other improvements over the winter. So, players can expect updates and enhancements to the game in the future.

Overall, RO-Scale BNSF Sunflower sub provides an enjoyable and immersive experience for train enthusiasts on the Roblox platform. Hop on board and enjoy your stay!
