I wanted to walk Mitsui Ashibetsu Railway (三井芦別鉄道, mitsui ashibetsu tetsudō), but yesterday, in those area haunted by a bear. So I change my plan, I came to Mitsubishi Mining Ashibetsu Office Exclusive Railway (三菱鉱業芦別工業所専用鉄道, mitsubishi kōgyō ashibetsu kōgyōsho senyō tetsudō). This railway connects 8.2km between Kami-ashibetsu Station (上芦別駅, kami ashibetsu eki) and Penke Sanko Station (辺渓三坑駅, penke sanko eki) on northeast, and started business in
The track starts Kami-ashibetsu Station and branch off from Nemuro Main Line (根室本線, nemuro honsen), through Mitsubishi Kami-ashibetsu Station. After it the track go over Sorachi River (空知川, sorachi gawa) with Sorachi-gawa Bridge (空知川橋, sorachi gawa bashi), but I know this bridge was removed, for this reason I chose opposite shore to start.
The track that finished cross the river enter to Penke Tunnel (辺渓トンネル). Yippee! There is tunnel…what a…!?
I can hear. I can hear scream of tunnel killed by earth pressure. I scream too, “I can’t enter!”.
I lost time and go a long way round because of collapse. This side had buried too, but it looks artificial backfill.
Ahead of Penke Tunnel, Penke-gawa Bridge (辺渓川橋, penke gawa bashi) had removed except for pier. I must to make a detour again.
I made a detour with national road, site of track had removed by national road. I wonder if all highlight had removed. Nope, it’s from here that Mitsubishi Mining Ashibetsu Office Exclusive Railway is going to show those highlight.
National road and track are branched off at the same time as I come in ravine of Bannosawa River (盤の沢川, bannosawa gawa), there is the railway bridge at here.
No.1 Bannosawa Bridge (第1盤の沢橋, daiichi bannosawa bashi) is 3 span concrete bridge. I think it is made without reinforcing bar because I can’t find reinforcing bar in this damaged and split section.
No.2 Bannosawa Bridge (第2盤の沢橋, daini bannosawa bashi) on upstream removed by construct of forest road, but 3 span concrete No.3 Bannosawa Bridge (第3盤の沢橋, daisan bannosawa bashi) remain on more upstream. This line opened in , but I get the impression that prewar or during the war because no decoration, short span, and solid-spandrel.
Across this bridge, snow is too thick so I stopped to walk.
