Kato recently announced error on 10-1231 Orient Express.
The detail was that Kato missed painting 1 layer on the emblem of car #12, which is included in add-on set.
Very small difference and KATO even didn't notice this error until a report from an end user from one of retailer. Just put a photo to compare. Car on top having error while the one at the bottom is correct car.
ModelTrainPlus already got replacement parts for this and notified to all the customer purchased.
