バイカル・アムール鉄道
Construction of the AYaM began in the 1930s, with the construction of the spur line from Bamovskaya to Tynda (then known as Tyndinsky) as part of the planned construction of the Baikal–Amur Mainline. This section began operation in 1935, but was then dismantled in 1940-41 as the Second World War saw the BAM project cancelled and the rails were reused for other projects closer to the front.
