Half relief is then a nice solution. Over a length of about four meters, it should look like the station is situated in a city. Using ready-made plastic building materials would be too expensive. As an alternative, a nice background can also be created with cardboard. The company Jowi provides CDs with a number of building plans. You can print these out. For this, you need a printer that can handle paper up to 300 gr/m2. This is the thickness that is usually used for building plans.
The prints always have a flat surface at the front. The relief is in the side walls and roof. This makes the houses stand out from the background. By making multiple prints of the image, you can add extra relief yourself. To start, I print the image three times: once in color on 300 g/m2 paper, once in color on regular printing paper, and once in black and white on regular printing paper. I cut out the 300 g/m2 print and score and fold the edges. Then, I glue gray cardboard of about (>=) 1 mm thick into the folded model. Next, I cut out all the windows. Behind these, I glue the second print. Finally, I glue the last print onto black paper. I only cut out the window panes from this one and glue them onto the model last to prevent any light from shining through. I also cover the walls and roof with gray cardboard and continue gluing the model together. By building it in this way, the model immediately looks better and can be equipped with LED lighting. You can decide for each model whether you want to add some extras, such as a balcony, staircase, signboard, roof edges, window shutters, etc. Simply make an extra print of that part and expand it with some cardboard. Finish all the edges where paper or cardboard is visible with markers or paint. It is especially recommended to color the edges around the windows before gluing the second print onto the model.
