There must be some changes on the locomotive itself to make it closer to Polish version: A and B - must be removed C - there is a box instead of more complicated equipment D - must be more flat E - those items do not exist on Polish locomotive but I do not think I will be able to remove it properly :-( They stay in place. F - top light must be removed. Two bottom lights must be bigger. Some "cuts" on the model as well as added box ithe front of the cabin. To make the box I used some scrapbox item (unused and modified part of KIBRI kit).
