For coupling sand trains for the purpose of restoring the uranium-ore mines in the Ronneburg region, the Wismut AG was still using their V200 which had been directly delivered there in the 70ies. With the increasing age and the removal from service at the DBAG, economic maintenance of this series was no longer ensured. Therefore, three machines of this series were taken over and re-motorised in Cottbus. They have the fleet number V300 001 - 003 and are painted in mint-green/grey.
