(5) Peaceful solution: Summoning the funicular Deus Ex: HR Guide
Last update: 11 May 2016
If you don't plan on stunning the enemies, you have to - in accordance with the previous hint - use camouflage (Cloaking System) to reach the funicular summon button and afterwards quickly back out to a safe spot. I wouldn't recommend using the upper balconies #1, as at least one enemy might decide to check them out. A much better solution is hiding inside one of the ventilation shafts #2. Be patient and ignore the new mercenaries that will appear in the area. Get out of the cover only after receiving a confirmation from Pritchard that the funicular has arrived. Turn on the camouflage again and head towards the train cart.
Reward: 250 EXP + 750 EXP for staying undetected.
If you decide to actively engage in combat in this room, start off by dragging the bodies of the neutralised mercenaries into a more secluded place (e.g. ventilation shafts). It will prevent other enemies that will soon appear here from waking them. At the same time pay attention to the big weapon depot located beside the funicular entrance (screen above). I'd recommend taking the concussion mines and mine template (the latter ones work best when combined with a gas grenade, forming a gas trap).
Now you can act in one of two ways. If you don't have anything against using mines, you can place them beside both room entrances #1 #2. However be sure that you're using mines that will only knock out, not kill enemies. If you don't want to use mines, focus solely on summoning the elevator and don't plant them.
Reward: 250 EXP + 750 EXP for staying undetected.
After pressing the button, be ready for more mercenaries to come. If you've planted mines, each enemy - or at least most of them - should get knocked out #1. If you haven't planted any traps, it's best to lurk for the enemies at the upper balcony #2.
Wait for one of the mercenaries to appear on the balcony #1 and neutralise him without alarming his friends downstairs. The nest enemy should soon reach the ventilation shaft entrance north of the funicular entrance. It would be good to attack him from the shaft's side #2.
Only two enemies left to take care of in the main room. As their paths and fields of view often cross, it would be good to attack one of them from a distance #1 and stun the second one in melee combat #2.
Regardless of the decisions made thus far, you have to wait for a confirmation from Pritchard and enter the funicular after receiving it #1. Once inside, turn right and use the control panel #2.
Reward: 2750 EXP.
