It was regularly used to carry AF (frozen food) containers: while the Conflat L, which could carry three smaller containers for bulk powders, was also produced in large numbers.
The Conflat B wagon could carry 2 AFP (frozen food) containers.
These were slightly wider than the standard AF containers, and were designed to carry loads on pallets.
Unlike normal wagon loads, containers were only listed to carry furniture or goods (unless they were refrigerated containers, which carried frozen products kept cold by ice) which needed to be placed on a specialist flatbed wagon which had train braking capability due to the fragile nature of the products carried.
