# Toyohashi Railroad Atsumi Line

The Toyohashi Railroad Atsumi Line (豊橋鉄道渥美線, Toyohashi Tetsudō Atsumi-sen) is a railway line in eastern Aichi Prefecture, Japan, operated by the private railway operator Toyohashi Railroad ("Toyotetsu"). The line runs from the centre of Toyohashi, traversing the centre of the Atsumi Peninsula, a largely rural district noted also for its hot spring resorts and marine sports as part of Mikawa Wan Quasi-National Park. The line is entirely within the cities of Toyohashi and Tahara.

## Operation

The northern terminal station for the Atsumi Line is located at Shin-Toyohashi Station. Most trains run to the southern terminus at Mikawa Tahara Station at approximately 15 minute intervals, with the exception of the last train departing Shin-Toyohashi Station. There are no express trains on the line.

## History

Plans to construct a railway going across the Atsumi Peninsula have been planned since the 15th Division was stationed in Toyohashi. 12 people with the financial help of Keijiro Amemiya planned building a light railway in 1909, but the railway wasn't constructed, and the permit expired. The Amami Light Railway was established in 1918 by locals, but was split on whether the railway should be operated by the government or not, and the privately owned Atsumi Electric Railway (渥美電鉄, Atsumi Dentetsu) was established in 1919 as a result. The company began operations on January 22, 1924 between Takashi and Toshima, electrified at 600 V DC. The line was extended to Kambe in March and to Mikawa Tahara by June 10 of the same year. In the opposite direction, the line was extended to Shin-Toyohashi by May 1925. On April 10, 1926, the now-defunct section of track from Mikawa Tahara to Kurokawahara was completed. Construction of a proposed extension to Mikawa Fukue commenced in 1939, but was later abandoned due to World War II.
On September 1, 1940, the Atsumi Electric Railway was merged into Nagoya Railway. The section between Mikawa Tahara and Kurokawahara and many stations were suspended on June 5, 1944, as an austerity measure. On October 1, 1954, the Toyohashi Railway was spun out from the Nagoya Railway as an independently operating subsidiary. The suspended section from 1944 was permanently closed November of that year. Three P-51 Mustang aircraft attacked a train heading to Toyotashi on August 14, 1945, killing 15 people and injuring an additional 16.
Express train operations began in October 1, 1965. All freight operations were discontinued from February 1, 1984 and express train operations were discontinued from September 1, 1985. On July 2, 1997 the electrification system was upgraded to 1,500 V DC.

## Rolling stock

As of April 2015, the line is operated using a fleet of ten three-car 1800 series electric multiple unit (EMU) trains. These trains were modified from former Tokyu 7200 series EMUs. All trains are configured for one-man operation.
Since 2013, the trains are each painted a different colour and carry the names of flowers, as follows.
