The London firm Priestmangoode created an interesting framework for double-deck trains, which can carry more than 1,000 people. The design of this miracle technology is done in a modern style with a few hints of minimalism. The two-storey train is virtually provided with all the conditions, you will find comfortable sofas, restaurant, mini bar and more. One of the main advantages of this train is its windows, which provide an excellent overview of the surrounding countryside. Unfortunately, at the moment it is only a framework, and it is unknown when the project will go into mass use.
