In November 2017 a new movie Murder on the Orient Express with Director Kenneth Branagh will be released, see this thread https://ogrforum.com/...n-the-orient-express. The locomotive used in this movie is the restored and brought back in running order SNCF 241A65 mountain; in the movie it has a snow plow attached. MTH has previously issued this locomotive and in catalogue 2015V2 MTH announced a re-release (product numbers 20-3606-1 and following numbers) which has still not appeared. I assume that MTH could, with using the publicity of this movie, sell a large number of these locomotives, so you might consider to start production.
