TheToyohashi Railroad Atsumi Line (豊橋鉄道渥美線,Toyohashi Tetsudō Atsumi-sen) is a railway line in easternAichi Prefecture, Japan, operated by theprivate railway operatorToyohashi Railroad ("Toyotetsu"). The line is entirely within the cities of Toyohashi andTahara.

Plans to construct a railway going across theAtsumi Peninsula have been planned since the15th Division was stationed inToyohashi.^[2] 12 people with the financial help ofKeijiro Amemiya planned building alight 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.^[3] The company began operations on January 22, 1924 betweenTakashi andToshima,electrified at 600 V DC. The line was extended toKambe in March and toMikawa Tahara by June 10 of the same year.^[4] In the opposite direction, the line was extended toShin-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 toWorld War II.^[5]

On September 1, 1940, the Atsumi Electric Railway was merged intoNagoya Railway (Meitetsu). The section between Mikawa Tahara and Kurokawahara and many stations were suspended on June 5, 1944, due to steel shortage.^[6][7][8] ThreeP-51 Mustang aircraft attacked a train heading to Toyohashi on August 14, 1945, killing 15 people and injuring an additional 16.^[9]

On October 1, 1954, the Toyohashi Railroad was spun out from the Nagoya Railway as an independently operating subsidiary. The suspended section from Mikawa Tahara to Kurokawahara was permanently closed November of that year.^[10] The timetable was revised on October 1, 1965 to introduce a express services that runs 18 times a day. This express service was abolished on September 1, 1985.^[11] All freight operations were discontinued from February 1, 1984.^[12] On July 2, 1997, the line's infrastructure was upgraded to allow railway electrification at 1500 V DC. 28Meitetsu 7300 series [ja] trains were transferred from Meitetsu to operate in the line. The line also began supporting the Meitetsu-styleautomatic train stop system.^[12]

As of 2024^[update],^[13] the line is operated using a fleet of ten three-car 1800 serieselectric multiple unit (EMU) trains.^[14] These trains were modified from formerTokyu 7200 series EMUs.^[15][16]

Since 2013, the trains are each painted a different color and carry the names of flowers, as follows.^[15]

There are a total of 16 stations on the line, with a signal station between Shin-Toyohashi and Yagyu-bashi.^[17]
