History
The line opened on 2 January 1945 as the freight-only Script error: No such module "Nihongo". operating between Shibukawa and Script error: No such module "Nihongo". (present-day Naganohara-Kusatsuguchi Station).[4] Passenger services were introduced as far as Nakanojō from 5 August 1945, to Iwashima from 20 November 1945, and to Naganohara-Kusatsuguchi from 20 April 1946.[4]
On 1 October 1952, the line was extended to Script error: No such module "Nihongo"., initially for freight only, but passengers services were also introduced from 21 June 1954.[4] Freight services between Shibukawa and Ōshi ceased as of 1 October 1966.[4]
Services on the section between Naganohara and Ōshi were suspended as of 1 November 1970, and on 7 March 1971, a new line was opened beyond Naganohara to Ōmae, with the entire line renamed Agatsuma Line at the same time.[4] The Naganohara-Kusatsuguchi to Ōshi line was formally closed as of 1 May 1971.[4] CTC signalling on the entire line was also commissioned at the same time.[citation needed]
With the privatization of JNR on 1 April 1987, the Agatsuma Line came under the ownership of JR East.[4]
It had been proposed[when?] to extend the line to Nagano, but geological exploratory drilling revealed extensive faulting beyond Ōmae, and as any extension would have required extensive tunnelling, this was considered impractical.[citation needed]
Yamba Dam construction
The construction of the Yamba Dam required the realignment of the Agatsuma line between Iwashima and Naganohara-Kusatsuguchi. Work on the diversion was well advanced when a change of government in 2009 resulted in the project being halted. Another change of government in 2012 revived the project. Services on the old section of the line were suspended following the last scheduled service on 24 September 2014 to allow commissioning of the new alignment.[5] The new alignment opened for passenger services on 1 October 2014.[5] The new route is 0.3 km (0.19 mi) shorter, resulting in the shortest tunnel in Japan, the 7 m (23 ft) Tarusawa Tunnel, being abandoned, although it is not inundated by the new dam.[6][7]
Points of interest
The Agatsuma Line is noted for numerous onsen hot springs along the route. The famous hot springs at Kusatsu are some distance north of the line, but several rural onsen such as those at Shima, Sawatari, Kawarayu, and Shiriyaki are more accessible.
Mount Asama, Mount Kusatsu-Shirane, and the Agatsuma Canyon can all be seen from the Agatsuma Line, though the canyon will be inundated when the Yamba Dam is commissioned.
