General Information (July 1951)
1. The Bulgarian Railways network covers a total of approximately 4,700 kilometers
subdivided as follows:
a. 39900 kilometers of standard-gauge railways; and
b. 80D to 900 kilometers of narrow-gauge railways.
The Sofia-Gyueshevo Line, via Radomir and Kyustendil (Spring 1950)
2. This is a standard-gauge,, single-track line; ordinarily traction is by steam engine.
The rails are German-made and are 8 and ]1 meters in length. The Sofia-Kyustendil
section was constructed prior to 1920; while the Kyustendil-Gyueshevo section was
completed in 1932. Four passenger trains run daily in each direction on this line.
3. The Sofia-Kyustendil line crosses the following bridges:
a. Bridge crossing the Struma River, an old bridge built at the time the line was put
into operation, never underwent any major repairs, has the following characteristicsi

Six kilometers west of Pernik, the railway line runs through a section 150
meters long cut into sandstone rock. The walls of this cutting are a maximum of
