About the Former Hokuriku Line Yamanaka Rock Shed
The Former Hokuriku Line Yamanaka Rock Shed (旧北陸線山中ロックシェッド, Kyū Hokurikusen Yamanaka Rokku Sheddo) is a rockfall shelter in Yamanaka, Minami Echizen Town, Fukui Prefecture, built in 1953 and entered on the national register as a Registered Tangible Cultural Property on 25 February 2016. It is a prestressed concrete structure 65 m long and 4.2 m wide that roofs over the old track to shield it from stones falling off the slope above.
It stands about 1 km northeast of the north portal of the Yamanaka Tunnel, on the Imajō side. It is the only Showa-era structure among the thirteen, proof that work to protect the railway on this stretch went on more than half a century after the Meiji tunnels were finished. It is owned by Fukui Prefecture.
Why the Yamanaka Rock Shed Was Registered
The Former Hokuriku Line Yamanaka Rock Shed was registered with the other twelve structures of the old line, as a structure that contributes to the historic landscape of the country. The Agency for Cultural Affairs counts it among the earliest prestressed concrete structures in Japan.
Prestressed concrete is concrete that has been put into compression in advance by tensioning steel tendons running through it, which lets slender members resist cracking and bending. The technique is commonplace today, but in 1953 it was still new, so this shelter is a valuable example from the period when it was first being adopted.
What to Look for at the Yamanaka Rock Shed
According to the Agency, a row of columns shaped to reflect the forces they carry runs along the river side, and slab panels span from a beam on top of those columns to the crest of a retaining wall on the mountain side. The logic is easy to read from outside: the hillside is held by the wall, the valley side by the columns, and the roof rests across the two.
The columns on the valley side are the thing to look at. Their form follows the flow of load, and their steady rhythm speaks of a design approach entirely different from the brick and stone of the Meiji tunnels. The Japan Heritage portal notes that remains of the Yamanaka signal station and switchback sidings survive nearby, so the Former Hokuriku Line Yamanaka Rock Shed sits among traces of how trains were worked over the pass.
Visiting the Yamanaka Rock Shed
The Former Hokuriku Line Yamanaka Rock Shed stands on the road along the old line, and cars and pedestrians can pass beneath it. There is no fee and no reception point. The roadway is 4.2 m wide, so if you are walking to look at the columns and slabs, watch for vehicles from both directions.
The shape of the columns is clearest from outside the shelter on the valley side, but that side drops away down a slope, so do not leave the road to get closer. When taking photographs, remember that you are on a road and choose a spot that keeps clear of traffic.
