After good experiences with them in the broad-gauge armored trains, the standard BP 42 was also equipped with two tank-carrier cars with removable Prage 38(t) tanks. The tub-shaped cars plus a folding armored shield protected the running gear. To remove the tank the pusher car ahead had to be uncoupled, an automatic Scharfenberg coupling was provided.

The kit consists of over 120 parts  with 

• 4 section roadbeds
• 38(t) Ausf.E/F tank included
• Newly tooled parts in accurate detail
