Im using Floor Plan Creator by Marcin Lewandowski, free with watermarks when you save as image, on a android phone. The projects will remain on your phone, but the program needs to be bought to be able to save as a project file and save as image, png or jpeg without the watermarks.
Below, the images are put on levels, from the bottom to the top.
Mobile phone flash shows the ,,metalic,, parts, being paint. The second locomotive is missing the top part and will be modified. The bottom long plastic piece can be removed.
Kingpin texture shows a poster of a locomotive and on its tale is a transport wagon. A narrow vertical shadow between the locomotive and the transport wagon is on the texture. The next two textures of a train wheel are the same, the left texture having a shadow on the far left of it.
