History
The Otaki Line was opened in 1955 by Shimakyu Railway, running their mainline trains into the Ginza financial district. At the time, Otaki was a sleepy residential town, with the trip to Misato requiring a transfer to the Tram network. Therefore, in order to connect to the financial and administrative districts of Lamtsu, the Otaki Line was constructed to Ginza Station, being the first subway line in Lamtsu and one of the earliest railways in Lamtsu. Although MCR is often credited with being the first railway company in Lamtsu, many other companies ran their Main Lines into Lamtsu, just not into the Central districts. The Sakura Railway company for example ended it's line at Otaki as well.
The Fukaaura Line, which is effectively an extension of the Otaki Line, has cross-platform transfer with the Namboku Line at Fukaaura. The line shares it's line code (line 3) with the Otaki Line. All Otaki Line trains continue to Fukaaura, so some passengers from the Namboku Line change trains at Fukaaura if they are heading for Ginza.
