There are two gizmos on the back of the Leo 2A6 turret I'm am trying to figure out what they are. First, on the rear of the turret itself, on the TC's side are two objects. They are kind of angular and look to me like "wheel" chocks. The other two are mounted on the rear of the storage baskets, one on each basket. Ones in the Tamiaya kit look like they are of three sections with a circle in the center of each section. Reminds me of a US traffic light with red/yellow/ green lights. Some sort of convoy lights? For my "What If" Colombian Army 2A6 I am planning on putting an A/C unit on the back or the turret and water can racks on the baskets. Need to figure out where (and if I need to) relocate these things.

According to the caption, these are the (empty) wheel chocks mounting brackets :

The "wheel chocks" are called "Seitenfestlegekeil". Their are attached under the track with spikes and the side going upward prevent the track from sliding sideways.

The German caption uses the word "Hemmschuhe" that's why I've used the words "wheel chocks"

In that case, shouldn't there be more of them?
Two means one per track?

Going from memory here but I think they are used for rail loading. They help prevent lateral movement of tank on the car. They were anchored by the spikes by driving over them.

But that would require a lot more than the two carried on the rear of the turret. Two of them is enough to make it more difficult for the tank to roll in one direction (downhill).
To stop a tank from sliding to either side of a railway waggon requires at least two for each side.

The tracks overhang the width of the waggon. One short sequence shows "Unterlegkeil" being placed in front of the track. There are no such objects on the waggon for the tank/track to roll over.

Now that I think of it the tracks hung over the side as it was so it wasn't for lateral shifting. Like I said was going from memory. No idea why only two though.

It is common to place one chock against a roadwheel on each side of the vehicle to prevent the vehicle moving whilst at rest.
It sits on the track itself with the curved side of the chock resting against the roadwheel rubber (The chocks face different ways on each side, so in theory the vehicle won't roll in either direction).

Not sure how many Seitenkeile are in the rear turret stowage, but I think that the other two are carried in the turret stowage box. Saw on Saturday Bradleys and M113A3 loaded on a train. M113`s were just secured by ratches and straps. Bradley got ratchedstraps and spikechocks. Interestingly, Bradleys got extra grounding wires.

Train loading video from "Grantiger Löäwe" exercise. From the 2:24 min. mark, you can briefly see how the wedges/chocks get attached.

Thanks, Guys. Now that I know what they are I can figure out where to relocate them. If they were something that wasn't of much use in a hot, tropical environment I would have left them off. (I have added a storage bin on the front. Respotted the track links to the lower plate and left the ice cleats off. Not much use for those in the jungle.)

The teeth on the bottom of the chocks are to sink down into the wood on a railcar. You'd drop the stabilizers at each corner-to near the rails. Then you'd drop the flaps between cars, ground guide it along the train,to your car. Then a German Conductor would take over. Place 2 chocks in front of the tank, move the tank forward, pushing the teeth in, then jam the 2 in the back and roll back the tank to sink those. Then Chains. M-1, hung over about 6-8 inches on either side from what I recall.

They didn't just use them on trains. On our wheeled vehicles we chocked every time we stopped no matter the surface, asphalt, concrete, dirt, sand, gravel, mud. First thing the driver did was hop out chock a front then a rear wheel. The armor guys did the same, tanks, apcs all got chocked when they stopped moving. Never could figure out if it did much good on the track vehicles with their weight and ability to drive over bigger obstacles than a chock block but the Army had it's rules.

I never understood it on concrete.

Befehl ist befehl.I don't know if it is just a Nevada thing , or country wide but service vehicles .... telephone, electric co., water service .... have to turn on their amber lights and put out a road cone whenever they stop, be it to work or get a coffee at Starbucks. Rules. Thought .... and keep in mind I'm a Civilian E-Nothing ..... Tracks might go over big obstacles but that is under power. Chocks might work under a static load.

The type chocks you show are not the same type depicted on the Leopard in question. Here is a video of an example. They are shown at the very beginning of the video.
You can see the crew using a tankers bar to pry them out of the wood on the bed of rail car. Driving over them was what anchored them in the car. When you drive over them you only drive on the flat portion.
I did count 4 on later viewing. What I failed to recall is that they were placed on inside of tracks when loading.

Around 2:30 you can see the crew stowing them. Normal front and rear chocks are of course used as well when loading.

Exactly
The things used for securing the tank on a railroad waggon is not the same as those hanging on the turret. / Robin
