"The world" is huge, it takes roughly four hours to travel from the northernmost point to the southern terminus along the in-game mainline. The map spans 16k x 8k, and at its heart lies the Great Central Mainline, a route I built to connect 16 of the 30 largest cities across the region. Over time, this grew into a living network that now carries both passengers and freight with their own systems and routines.
Freight operations stretch the entire length of the line, running on a 24-hour cycle, while passenger services follow a dedicated timetable with peak running in the morning and evening. There are three depots across the network currently - one at the southern terminus in Great Slarfingfield, another at the northern end in Overtwood that services the northern line, and a central marshalling hub at Wruwood, strategically placed between two vast mountain passes. Wruwood acts as the operational heart of the network, where goods trains are sorted while passenger expresses pass through the station. Passing loops can be found throughout the route, with more to be added over time. Currently, all passenger stations feature two platforms, except for Saningworth, which has three, with the centre line doubling as a holding road for goods trains when required.
Recently, the network took a major leap forward with the completion of the South Eastern Mainline, stretching from Mennway-on-Hill to Gundington, where it meets the Great Central at Fredham Junction (a future station is planned there) leaving again at Mudingury Junction. This new artery now means 28 of the 40 largest cities on the map are connnected, creating a continuous service across the southeast. It’s fully functional but still in its early stages, there’s no timetable or depot yet, and it marks the beginning of a much larger expansion phase.
