Lithuanian Prime Minister Algirdas Butkevičius and European Commissioner for Transport Violeta Bulc inaugurated the first completed section of the Rail Baltica standard gauge line with a ceremony at Kaunas station on October 16.

Rail Baltica envisages the construction of a 1435 mm gauge corridor linking Poland with Lithuania, Latvia and Estonia, and potentially Finland via a 60 km tunnel.

The first section to be completed is a 1435 mm gauge line from the Polish border to Kaunas, which has been built alongside the existing 1520 mm gauge line from the former break of gauge at Šeštokai which has also been upgraded. The project is designated Rail Baltica I, with Rail Baltica II referring to the proposed 728 km double-track electrified line on a new alignment from Kaunas to Tallinn which is estimated to cost €3·68bn.

You see a dual gauge track in the photo. It is effectively a 1435mm and 1520mm tracks gauntleted together on the same trackbed and ties.

Bangladesh has hundreds of km of dual gauge track of 1000mm and 1667mm tracks with three rails, one shared rail between the two gauges. The one in Lithuania and Latvia is a 4 ril system because 1435 and 1520mm are not different enough to be able to be handled by three rails.
