Panzerjägerwagen Vol.1
The BP44 armoured trains series included a number of improvements over the BP42 with the Pz Kpfw 38(t) units replaced with Panzerjägerwagen which featured a Pz Kpfw IV Ausf H turret armed with a 7.5cm KwK L/48 gun. This was also known as Panzerwagen IV auf Zugwagen. Typically these were placed at the front and rear of the armoured train to maximize firepower. Some BP42 were retro-fitted with Panzerjägerwagen.
