Would you be able to make the double deck city shuttle trains from Austria? Such as these: https://upload.wikimedia.org/wikipedia/commons/thumb/4/4d/2018-07-14_AT_Wien_12_Meidling%2C_Wien_Meidling%2C_%C3%96BB_86-33_102-3_%2849104473828%29.jpg/640px-2018-07-14_AT_Wien_12_Meidling%2C_Wien_Meidling%2C_%C3%96BB_86-33_102-3_%2849104473828%29.jpg

There are also those with the Cityjet design, however I like the first one better: https://image-service.web.oebb.at/www.nightjet.com/.imaging/default/dam/reiseportal/hero-teaser-2560x800/zuege-fahrzeuge/dosto-upgrade.jpg/jcr:content.jpg?t=1621414142588&scale=0.5

You are the best rail-related content created out there and I would love to see you making one of those! These are just impossible to find in the workshop
