All my engines and rolling stock

Above are all my engines and rolling stock. I currently have 5 engines - Mikado, Bavarian, Jaegermeister, Starter Loco, and my new lovely Rail Zeppelin.

I got them all into this case, and the top closes reasonably, but I need to put in some sort of dividers or something to be able to better keep them from rolling about, as it quite evident by the Zeppelin seeming to wish to launch LOL!
