A major part of the narrow gauge line from Suwon to Inchon ran through Ansan and surrounding area. This area was until 25 years ago country side: none of the buildings in these pictures existed at the time! Even by the end of the existence of the line, in 1995, most of this area was still country side, although most of line 4 had already been built.
This series of pictures is the line in Ansan from a point between approx. Handaeap Station (한대앞역) and the (future) Sari Station (사리역) under the Yongsingoga Road (용신고가차도) all the way to a point to the west of Gojan Station (고잔역). On the map below (copyright: Naver, this is the location of the map) this is the route of the line 4 (the light blue line) between the two red lines, starting at 1 and walking towards 5. The grey line at 6 is the old narrow gauge line running towards Suwon (the top left of the map is towards Inchon, the bottom right is the Suwon side), but during 2013 and 2014 the new commuter line is under construction here, so nothing can be found there any more.
Near the present day Soraepogu Station (소래포구) on the current Suin (commuter) line from Oido to Songdo a long bridge of the former narrow gauge Suin line can still be found. This bridge is simply named “Sorae Railway Bridge” (소래철교) and as such can be found on the online Naver, Daum and Google maps.
The easiest way to reach this spot is to walk from Soraepogu Station (소래포구) towards the water front. Next to the waterfront the Sorae History Museum can be found, which contains a lot of information about the railway, including an actual carriage from the line! In front of the museum is engine 7 (see a previous article).
The shortest individual stretch on the SuIn line which can still be found is the short part of the line within Suwon city between the main railway line and the Deogyeongdaero (덕영대로). This part of the line was the connection between the line running through Suwon to the station and the country side. The bridge over the main railway line was lifted after 1995, right after closure. But the track bed and everything else is still very visible there. The pictures were taken in July 2013.
This part of the line can easily be seen on Google Earth by zooming in at this location (switch to satellite view as well). The former line is the grey railway line in the map, and this part is the stretch between the (blue) railway line (the Korail main line) and the (yellow) main road to the right of the former line. The length of the track bed here can’t be more than approx. 100 meters.
