I am not sure if there is a bug with this scenario but after talking to Mrs. Edison at the station, when I look in all the cars, the suit case can't be found. In the below linked video at 27:55, the player finds the missing suitcase on a table in the bilevel coach behind the locomotive. When I play this scenario via Steam, the suit case can't be located on the table. I looked all over the train and it's nowhere to be found. Has anyone else experienced this bug?
