You are right. i am afraid that Marklin turtable is the only option anyway. I am not prepared to schratchbuild Z turntable myself... Sometimes we have to accept to compromize.
Here's an option for a smaller turntable (sorry folks, German only..) http://www.hapo-bahn.de/drehscheiben/holzabgedecktedrehscheiben/6cm/index.html Several options on a 6 cm (14 meters) turntable in Z. These around 200 euros including motor.
I did scratchbuild my turntable long time ago. The turntable bridge is 110mm long, a BR50 barely fits on it. The pit is a PVC 110mm drain pipe end cap. The bridge is build out of brass and styrene. Underneath is a dc motor with slow speed gearing. The bridge is directly attached to the axis of the gearing. Two contacts out of an old relay rotate under the pit over an pcb which is electrically split over the middle. This way the polarity on the bride is always identical to the connecting tracks, even when it is rotated 180 degrees. Unfortunately I had to store this layout temporary because lack of space.
Trebnica module needs to have a station. Oryginal Trzebnica had such a station building: The current state of the building is like this: Due to space limitations - I do not want my module to be overcrowded - I plan to have building in older form - without left additional wing. I think it will be also good to try to modell platform roofing with some green plants visible on the old post card. I started to search commercial offer but I was not able to find anything that is similar to that building. My decision is to kitbash based on KIBRI station: The start is similar to surgical job:
Follow up with kitbashing Trebnica station - changes in the base - some parts due to the fact that building has to be smaller were removed.
For the turn table I did one but I think it will be to large for your project. this one does turn but would need a motor attached to work! your project is coming along great! your work is out standing!
Base of the first module for Nojewo station prepared. Box made, base painting + some coverage of the ground, A little landscape shaping (according to the prototype). Track laid down....
Congratulations too, Pawel! A lot of very nice details and scenery with just a straight track...And what a difference if natural sun light can shine on our layouts.
There is some progress with next module. I added balast to the track, painted rails and weathered all the stuff. Grass on one side of the line have been planted:
New buildings for Trebnica module: Old resin model of warehouse by Artitec. New roof was added. Engine shop by Archistories made of carton. This is slightly rebuild - due to expected available place this is a mirror image of original design.
Hi, I like what you did with these nice kits. Love the doors to the engine shop. You might want to "dust" the roofs a bit? Matt
Thank you for the comment and suggestion. I think it is a good idea to weather a bit the roofs as well.
Small building for Trebnica module - this one will find it's place near bigger living house for railway personnel. Carton model by MBZ, painted and weathered:
This was probably the toilet building. Today it is not in good condition but it is really nice and "tasty": I found another MBZ production - similar shape, similar climate. I decided to have one on the module:
Yes. It is Lada Niva. Some years ago the most popular car used by forrest administration in Poland. This is Shapeways 3D printed model. https://www.shapeways.com/product/939ZM3QVB/lada-niva-z-1-220?optionId=43329548
