The Ome Line is a 3'6" gauge railway line situated in western Tokyo, which branches off of the Chuo Main Line at Tachikawa and follows the path of the Tama River to Oku-Tama. The initial section of the route is the section between Tachikawa and Haijima. Here, trains travel between the two busiest stations on the route, with Tachikawa sharing connections with the Chuo Main Line and the Nambu Line (And the Tama Monorail if set post-2000). At Haijima, trains can proceed along either the Ome line, or the Itsukaichi Line. There are also trains from the Hachiko and Seibu Haijima Lines that call at this station. As Haijima is located on the junction between the Ome and Itsukaichi lines, trains bound for Tokyo tend to be coupled/decoupled at this station, before continuing to their destination(s). The coupling/decoupling of trains at this station was something only done after the introduction of the 201 Series EMUs to the route in November 1982. Trains travelling north from Haijima on the Ome line will then proceed to Ome. Ome is the furthest that full 10-car consists can travel before the platforms become too short to accommodate them, 6-car consists however are able to proceed to Oku-Tama. The section between Ome and Oku-Tama is single track, with 4-car commuter trains operating in this section alongside the 6-car trains travelling to/from Tachikawa. Image from Google Maps. Key: Ome Line - Red Itsukaichi Line - Light Yellow Currently, the typical commuter trains seen on the route are as follows: Tokyo - Tachikawa - Ome (E233-0 T set (10-car consist) or E353 (9-car consist)) Tokyo - Tachikawa - Haijima (Couple/Divide) - Oku-Tama (E233-0 H set (6+4-car consist (divides at Haijima))) Tachikawa - Oku-Tama (E233-0 H set (6-car consist)) Ome - Oku-Tama (E233-0 H set (4-car consist)) Tachikawa - Itsukaichi (E233-0 H set (4-car or 6-car consist)) Haijima - Itsukaichi (E233-0 H set (4-car or 6-car consist)) Special commuter trains include: Minami-Yoshikawa - Tachikawa - Oku-Tama (E257-5500 (5-car consist)) Kawasaki - Tachikawa - Oku-Tama (485 Series "Hana" (6-car consist)) As far as this route goes, I would say that the E233-0 Series is the only one essential to the operation of this route, as all other trains perform similar services over the section of line that this route covers. Additionally, I would suggest including the Itsukaichi line, as it would vastly increase the number of potential scenarios that can be played across the route. Overall, the Ome Line by itself would be 37.2km (23.1 miles) long and feature 25 stations. Adding the Itsukaichi Line to the route would provide a branch with an additional 11.1km (6.9 miles) of track and 6 stations. ------------------------------------------------------------------------------------------------------------------------------------------ As JR Group are somewhat reluctant to hand out licences for their branding to most anime and video game studios, an alternative version of the route would have the route as it was in 1980 under JNR (a different company that still exists for the purpose of clearing the debts the Japanese railways accrued in the 1980s.) This would see a completely different variety of rolling stock being utilised and freight scenarios being playable across most portions of the route and trains not being coupled or divided at Haijima. Passenger services in this period would be performed by 101 and 103 Series EMUs, with the 101 Series primarily being confined to the Itsukaichi Line and the 103 Series mainly being used on the Ome Line; however some sources suggest that the two types did occasionally switch places on the two lines. Image taken from: http://lightmemoryofkokuden.web.fc2.com/1986101.htm The line also featured 4 freight depots during this time period. These were located at Haijima, Kori, Oku-Tama and Okuno (Itsukaichi Line). Up until 1982, all freight duties were performed by ED16 locomotives that were built in 1921. Three of these were preserved, however two were scrapped due to poor condition or lack of space and the last example of this locomotive is preserved at Ome Railway Park. On this route, scenarios would primarilly involve hauling limestone trains between Oku-Tama and Haijima. All pictures taken from wikipedia unless otherwise noted. TLDR: Two versions of the route are being suggested, one is set in the 2020s using JR East's E233-0 EMUs and the other is set in the 1980s using JNR 101/103 Series EMUs and ED16 Freight Locomotives. Length is 37.2km (23.1 miles) and has 25 stations with a possible branch line with 11.1km (6.9 miles) of track and 6 stations.
