Source of this photo:
"Report from the travel to the German's railway pioneers operating area, southern front, 13.9. - 16.10.1942" by Finnish Army Major, engineer U.Kivikuru.
Member of this Forum kindly located the document for us in the Finnish National Archives (folder number T 22470/124).
Here are some details about the project.
It had been referred to as Gniloje - Jewdakowo railroad. Gniloe (Gniloye / Гнилое) is a small village near Ostrogoshsk, where new railroad started (0.0km) - it can be found on the German map I uploaded earlier.
It had length of 28.5km and construction was divided into four sections with different German unit responsible for each one:
Bauabschnitt I - Eisenbahn-Bau-Kompanie 126 (EBK 126)
Bauabschnitt II - 3./Eisenbahnpionier-Regiment 6 (3./6)
Bauabschnitt III - Brücken-Bau-Bataillon 37
Bauabschnitt IV - 4./Eisenbahnpionier-Regiment 6 (4./6)
3000 pioneers and Org.Todd members were involved, together with 10000 Soviet POWs.
8 bridges were built, longest - Petrenkowo bridge had 462.2m, Michnowo brigde was second with 181.8m
Responsible for the whole project - construction manager Major Grambow.
