Construction of second rail link at port of Koper in full steam

Construction on the second railway line of the port of Koper stretching to Divača in Slovenia is advancing. The 27-kilometres long line project started construction works in May 2021 and is currently in the phase of tunnel excavation.

2TDK, the project’s manager, will complete construction works in 2025, while the line will be ready for use a year later. According to the port of Koper, the development is related to the “battle that the ports give on rail”, meaning that to be a successful port, you need efficient rail links.

The entire 27-kilometre Divača-Koper railway section will allow speeds of up to 160 kilometres per hour, comparable to modern European railways. The railway will rise from sea level to 430 metres in Divača, and three-quarters of the railway route will run in tunnels.

First 1,000 metres of tunnels

Currently, construction works focus on excavating tunnels that will allow trains to transit through the mountainous route to Divača. The contractors have already completed the excavation of the first 1,000 metres of tunnels. Until 2024, they have to dig a total of 37 kilometres of rail and maintenance tunnels. Finally, tender procedures for the construction of tracks and their electrification will take place in 2022.

A pity, that maintenance (repairing) devastatingly reduces track capacity, in particular now, on the contrary, promptly a 50% increasing is requested.
Regardless if against “optimised maintenance”, now utilisation of investments is reduced, by disturbing track activities, etc. A new, upgraded “Old Railway”, now urgently is requested! (Safely, calculable, again low, limited systems forces, thus sustainable, duly with proper safety factors, 32,5 ton axial load capacity, now is the timely.)
