Context: Cronulla railway station is the terminus station of the Cronulla line, serving the Sydney suburb of Cronulla.  It is served by Sydney Trains T4 line services.  The station is unusual in that the two platforms are situated end to end, rather than side by side, making it the second longest rail platform in New South Wales, after Albury. The Coonamble railway line is a railway line in New South Wales, Australia.  The line branches from the Main West Line at Dubbo.  It opened in 1903, and carried passenger traffic until the 1970s.  900/950 class railmotors were first introduced on the service between Dubbo and Coonamble.  It continues to carry goods traffic, predominately grain.  The disused historic Coonamble railway station is currently at risk of demolition due to vandalism and high maintenance costs.

The Osaka Higashi Line (おおさか東線 , Ōsaka-Higashi-sen ) is a railway line in Osaka, Japan, operated by the West Japan Railway Company (JR-West).  Before being named on August 23, 2007, the line was constructed with the tentative name "Osaka Outer Loop Line (大阪外環状線 , Ōsaka-soto-kanjōsen ) ".  Conceived in the 1950s during Japan's explosive postwar economic growth, it was planned as a grand "outer loop" of the city, using existing freight lines to link Amagasaki with Shin-Osaka, Suita, Awaji, Hanaten, Kami, Uriwari and Sugimotochō, with a newly constructed segment into Osaka's (then primarily industrial) Nankō Port Town.  However, with JNR's financial situation deteriorating catastrophically (culminating in its privatization) and continuing issues surrounding land acquisition and squatting by local residents on railway property, the plan was cut back to Shin-Osaka and Kami, terminating at Kyūhōji in the south.  (The Hanwa Freight Line, which would have carried the southern segment from Kami to Sugimotochō, was officially abandoned by JR Freight in 2009.)  The line will connect Shin-Osaka Station in northern Osaka with Kyūhōji Station in Yao, forming an arc around the eastern suburbs of the city, but currently only the southern half of the line, between Hanaten and Kyūhōji, is in operation as a connection between the Tōzai/Katamachi and Yamatoji lines. The Bessho Line (別所線 , Bessho-sen ) is an 11.6 km Japanese railway line in Ueda, Nagano, Japan, operated by the private railway operator Ueda Electric Railway (上田電鉄 , Ueda Dentetsu ) .

Although the company is the root of its holding company, Ueda Kōtsū (上田交通 , "Ueda Transport") , the group now mainly operates resort amusement facilities and bus lines.  Ueda Kōtsū is owned by Tokyu Corporation.  The railway line lacked funds to upgrade the infrastructure to meet the new safety standards, and separated to become the present company.
