"This has interesting building tecniques but some of which are quite simple. I like how the roof comes off and the toilet adds a bit of humor to the scene. Also, I like how the train is compatible with +PowerFunctions. It is a great build for experts and intermediate builders alike. It also allows people to use their imagination and build an environment that would match a scene where the train could be (e.g. country, station etc.) Another good thig about this set is that it also fits with other trains in your LEGO City train sets and can fit in easily with the LEGO City Passenger Train (7938) and Cargo Train (7939). There is a lot of creativity involved in making a decent scene on the train with the figure."
