reserve "Armored" Train is actually not armored

[MrInside 1]

So I wanted to exfil with the train on reserve. 

Problem was someone was shooting at me from the other side as the train stopped, trough the train. As I got inside the shooting continued even though I wasn't visible. I run around in the train and saw 5 or 6 scavs(pretty sure). I laid down and the shots continued to hit me even though I was moving and not visible. 

 

Aside from a scav seeing me trough walls, be it a player hacking or a scav having supernatural sense. How tf is that even possible if it is supposed to be a armored train when a normal gun can penetrate the walls?? 

 

Unfortunately I didn't record and realized too late to do so. 

Really frustrating if you have big loot on you.

Armored does not mean it's invicible, right?
