Another issue with putting it at the rear is you're sacrificing the chance of properly defending the rear arc of the train. Sure you can put a couple of machineguns and sandbags there, but not a lot more. Having a box car, or even just an empty flatcar at the rear allows building up a decent strong point.
Probably not a huge concern while the train is moving forward, but as we know in 2000 Poland there's a LOT of bridges and tracks destroyed or damaged - the train will be motionless, or even travelling in reverse more often than not while repairs are made, or an alternate route found.
