 Russians constructed 30 km defence line with 2,000 railway cars. The Russians built a 30 km line of defence from more than 2,000 railway cars. This was reported by Deep State Analytical Community. The continuous construction stretches along the branch line from the railway station in Olenivka to Volnovakha and has about 2,100 wagons of various types. It is reported that the construction of this massive defensive line began in July 2023. For its construction, apparently, rolling stock was used, stolen, from the temporarily occupied territories. Such a defensive structure, which in fact represents a solid wall, is a very serious obstacle in the way of advancing troops. Given that some sections of the railway track are built with a high roadbed, such a defensive line is a full-fledged defensive shaft. It is possible to overcome it only after large-scale engineering works, disengagement of wagons, removal from tracks or movement to another place. However, these engineering works will be accompanied by the counteraction of the Russians. In addition to problems for Ukrainian troops, such a line of defence also creates problems for the Russians themselves. Logistics for advanced positions can be difficult due to an obstacle. In addition, such a barrier creates an obstacle to maneuver. This is a very specific engineering structure, the effectiveness of which is difficult to assess. The idea is clear, an obstacle to the advancement of the defence forces. It can be considered as a separate line of defence because it is extremely difficult to damage, move or blow up a 30 kilometer mass of metal and the movement of equipment through such a blockage without breaking through the corridor is impossible, writes the deep state team. This is not the first time the Russians have built huge engineering barriers as part of a full-scale Russian-Ukrainian war. In April 2023, it became known that the Russians built a solid 70 kilometer anti-tank ditch in Zaporizia, which stretched from the village of Semenivka to the village of Marinovka.
