The Seiyo Shinkansen (西予新幹線) is a line of the Joban Shinkansen network, connecting Central South in Fuka, Joban with Lamtsu in Sorano, the two biggest cities in the area. The line is jointly operated by Harmony Rail Transit (Joban) and Kowloon-Canton Railway Company. Harmony Rail Transit (Joban) operates the line far into the borders of Harmony Rail Transit (Lamtsu). it is a southward continuation of the Tohoku Shinkansen and serves other major cities such as Fung Yuen. The Shinkansen route is one of the shortest in the world, with the distance between some stations being comparable to the North-South Line. The Galaxy completes the trip from Central South to Lamtsu in 20 minutes, reaching a maximum speed of 200km/h. The Nagano and Shima Shinkansens continue the route eastwards towards Joetsu Prefecture.

History
The Seiyo Shinkansen was constructed to take traffic off the Fung Yuen and Ome Lines, and also provide competition to the Ome Railway Company's limited express services. The line was entirely funded by the Harmony Rail Group, and there were several different alignments proposed.
The first proposal was a half-shinkansen line, with the section from Central South from Fung Yuen being newly built for a Shinkansen. After which it would switch to a mini-shinkansen line using the Fung Yuen Main Line and continue using a similar alignment to the current day Ojika. This would have been called the "Fung Yuen Shinkansen" and would have been operated by Harmony Rail Transit (Joban) instead of Harmony Rail Transit (Lamtsu). HRT Lamtsu rejected the idea, as it would not receive any extra money from the project, and would even lose money from the reduction of Aotetsu services which had to pay to use the tracks into Misato.
The second proposal was a full Shinkansen line, with new tracks being built from Misato all the way to Central South paralleling the Ome Line, with the line to be called the "Lamtsu Shinkansen" or "Lamtsu Railway". The Ome Railway Company protested hotly against this, and bought huge swathes of land to prevent construction of this service, and therefore this proposal was dropped.
The third proposal was also a full Shinkansen line from Misato to Central South, but skirting to Fung Yuen via Ojika. The line would follow the Mihara Line from Misato to Mihara, then continue north-west to Ojika. This time, Nantetsu objected to this, as they had a very lucrative business model that revolved around the development of the Haebaru region due to the traffic passing through. Furthermore, there was no space at Misato for any new station developments.
The time between the third and fourth proposals was 10 years, for some unknown reason. In 1995 Harmony Rail Transit (Lamtsu) put forward the most complete proposal so far, yet which was also very ambitious. This alignment would first skirt to Tai Hing, avoiding all the more populated northern areas, before heading north to Ojika Junction (now Shin-Haebaru). The line then would run parallel to the Fung Yuen Main Line until Fung Yuen, allowing Harmony Rail Transit (Joban) to demolish the massively unprofitable portion of the Fung Yuen Main Line, and then cutting eastwards to Central South, using the right-of-way that had been reserved for the Tohoku Shinkansen 15 years prior. This plan however, had support from Nantetsu, who had by then diversified from railway operations and was mostly a real estate company. They would fund 40% of construction costs on the condition that all serviced stopped at Ojika Junction. The line would be operated by Harmony Rail Transit (Joban), who were filling to foot 20% more, and the remaining 40% would be funded by a loan from the Lamtsu Development Bank.
