No, with 8 people in that spot, there is a non stop barrage of gunfire, which means constant knockback, and therefore trains are impossible to even get started. Now you think a deformed in the lead might be able to start a train, but nope, with all 8 guns directed at the deformed, not only is the deformed already slow, its slower while crouch walking, and even slower still while being shot at, and you can't just start jumping and hope to get in, because you need a bit of speed for the jumping in a crouch spot to actually work, so deformeds actually become a wall preventing other zombies in, and the deformed dies within 4 seconds like I said. I also said that the zombies did try to train, and it wasn't happening, and we were doing it right.
