I know a long time has passed since part 1 was released, and it's because i've not been really sure of what to include in this episode. Furthermore, it's never a good idea to rush a such big and effort-requiring project like this. The videos where recorded between 2016 and 2021

About track circuits:
Track circuits are a technology used for indicating if a section of track is occupied by a train. It practically implies leading a faint voltage (ca 7 volts in Sweden) in the first rail from one point along the line to another, where it's fed over to and lead back to the first point through the second rail. In this way, a sealed circuit is formed which is short-circuited when a train wheel axle enters this section. There are three track cirquits in connection to a level crossing in Sweden, of which the two first ones are leading from the crossing in both directions to points enoughly far away for activation and lowering of barriers to take place before the train reaches the crossing after entering the circuit. The third one is short and located between the two previously mentioned, the section over the passage more precisely. This one is what allowes barriers to open directly after the last train car has passed. Some interesting links are following below:
