This afternoon we are releasing a Hotfix update for the Metro-North Kawasaki M8 EMU. After we released a patch for the M8 last week some players reported that the tail lights were not turning off. We would like to thank you for telling us this and based upon your feedback this Hotfix now fixes this. As usual, the hotfix will download automatically from the Steam client once released. The original patch notes can be found here if you would like to know more about the earlier patch - http://steamcommunity.com/app/24010/discussions/3/558754260593187829/#p7
