Use the railcar to push the train out of the way | Chapter 12: Regina Metro: LL Guide
Last update: 11 May 2016
Before you decide to get to pushing the train out of the way, examine the optional area to the right. Collect the filter and enter to handle several mutants (since this is going to be a fight at close quarters, I recommend that you use either a shotgun or a double-barreled shotgun ). Having secured the area, explore to find shotgun, ammo and military grade rounds.
Return to your car and approach the train. You need to take into account that, as you are pushing the train, there will be mutants appearing behind your back every now and then. I recommend that you react to that as quickly as you can by first shooting the mutants in the distance (screenshot 1), and then at those that managed to catch on to your car (screenshot 2).
The fact that you are pushing the train does not mean that you should neglect the side areas that are suitable for a more thorough exploration. An entrance to one of such areas has been shown in the above screenshot. Explore the abandoned barracks to find there, among others, a filter and a rifle.
You will recognize the entrance to another optional area by green mushrooms growing out of the wall. You need to keep vigilant as the tunnels serve as a den of mutants. After you come close to the den, start eliminating the monsters, and be prepared to be attacked from various sides. (you can position yourself next to the collapsed tunnel to make it easier to fend off any attacks). After you are done, search the area for supplies and Artyom's diary page shown in screenshot 2.
Return to your car again and start the last part of the pushing process. After it rolls over the track to the right, approach the switch and interact with it. You can now move forward while gaining speed to ram through the wooden barricades, which will end this chapter.
