I have already finished a few cars for my diorama and started work at the base. Just a few words about my plan:
This part, 240x45 cm size, will contain one track - spur track - with BR 86 locomotive and 5 cars, ruined service building with a crane and coal supply for steam locomotives, water crane, some other small buildings and adds, workers loading up a car, service staff etc. Whole diorama, about 240x 200 cm, will have about 6 or 7 tracks, second and third track will be for transit, with trolley wire, because I have 1 electric locomotive already. Suppose some small train drifting or something else(have a few more cars, others are coming and might be use for my Leopold gun or Morser Karl on carriers). Forth and fifth track ending in steam locomotives service building (have BR 64, BR 86 from Trumpeter coming next year, have armoured BR 52 with wannen tender, planned in three-coloured camo, another BR 52 with Vanderbilt tender, planned in grey and yellow strip camo). There will be also fully armoured train. Trumpeter has announced 5 armoured cars for next two years and armoured BR 57 steam locomotive as well. And the Dora at the back. Some other small buildings, all that stuff and mess you just can imagine in busy German military railway depot, some small vegicles, figures (really pain for me to paint) - that is incomplete description of my idea.
I started with kits last year and this is my very first diorama ever, so I am not sure about upcoming results - however, you were warned

I will sort out my stuff and bring some news soon.
Cheers
