Chūō East Line So far, Dovetail Games has understandably focused on creating content from the main 3 countries in TSW, the USA, UK and Germany. However, Dovetail Games has stated that they want to expand into new territories for Train Sim World. Japan would be one of the best places for TSW to feature as it has an extensive railway network with a variety of different locomotive types. As a first route, I believe that the Chuo East Line would make a good choice. The Chuo East Line is operated by JR East and operates between Tokyo and Shiojiri, a distance of 222 km. If that distance is too much, the route could be split into two sections with Kofu as the half-way point at 134 km from Tokyo. The route has a speed of 130 km/h and many stations, creating potential for many commuter services. There are also express services such as the Azusa along with many freight services also. Locomotives JR East E257 The JR East E257 is the principal InterCity train on this route operating the Azusa, Kaiji, Chuo Liner and Ome Liner services along the Chuo line. It has a maximum speed of 130 km/h, the same as the line. These locomotives are set to be replaced in 2018 though so if this route is made it may contain the replacement locomotives. JR East E351 The E351 is another type of Intercity train used on this route. It operates the Super Azusa limited stop service along the whole length of the route. Like the E257, the E351 has a maximum speed of 130 km/h and will be replaced by March 2018 by newer traction. JR East 211 Series The 211 Series operates local commuter trains along the route. They have a maximum speed of 110 km/h, slower than the InterCity locomotives JR Freight EH200 Freight services along the route are operated by JR Freight, the main freight operator in Japan. JR Freight uses the EH200 locomotive due to the steep grades on the route (up to 2.5%). A variety of different freight types are transported along this route. Conclusion The Chuo Line in Japan would make a good choice for expansion out of the three main countries in TSW. There are a variety of InterCity, commuter and freight services which operate along the route. The route travels through mountainous regions, with grades of up to 2.5% which is a contrast to the GWE, Rapid Transit and NEC routes which are broadly flat. The route also provides opportunity for further expansion as many types of locomotives other than the ones mentioned above operate along this route.
