Even though the direct main line via Dęblin is scheduled to reopen for TLKs from 9 June 2019, two pairs remain scheduled via this route until 14 October 2019. This 52km section had reopened on 11 June 2017 for diverted Warsaw - Lublin services due to long term engineering works.
Dęblin – Stawy
 (ERA178C1, E11) PL19/506
There are two passenger routes from Stawy, which connect the Łuków line to the north and south ends of Dęblin station, forming a balloon loop. However, only the line at the north end line is shown in the Quail map. The normal mode of operation is for trains from Łuków to Dęblin to arrive at Dęblin using the southern route, even if they are continuing south and need to reverse in order to do so. Trains from Dęblin to Łuków use the northern route.
