Hello.
I present the till now upgrade of the bufferplank of the SBB CFF FFS, Rilns, wagon with tarpaulin (Schiebeplanenwagen), that will be converted to greek ΟΣΕ/ΤΡΑΙΝΟΣΕ:
22.09.2013:
1./ Test of the distance between the end of the buffer-plates and the end of the hook of the screw-coupling. According to FREMO: 87 / PROTO: 87 standards, it must be 3.9mm. For the one side is counted exactly 3.9mm, and from the other side 4.1mm, However with this difference of 0.2mm, the coupling was operational and had flexibility in 4.1mm, when I coupled it with i.e. the Ψ3. It wasn't "stiff", so it won't have any problems on curves, i.e. between 1000mm - 3000mm of radius.
2./ Also, you may see the already handmade shunting-handrails (Rangierergriffe). I explain their construction in the post of my Ψ3. Also, I made the holes a little wider, so as to fit them exactly like the prototype, because as you see in the pic, they are only attached temporary, not fitted.
3./ I have tested it with sprung-buffers with plates of sizes: 550mm x 340mm, because I didn't have the type (Ausführung): 450mm x 340mm. These will be bought for the final assembly.
4./ The UIC-steps (Rangierertritte), are already soldered / completed out of etched Nickel/Silver, Rangierertritte UIC-Bauart, 2
superfein geätzt, από ÜDO BOHNLEIN, Art. Nr.: 530 16 34010), and they are fitted temporary.
5./ The rolling on the tracks with wheels: PROTO: 87 / FREMO: 87 (from WEIMANN, Art. Nr.: 591 18 11392 S24.7, wheel-diameter: 10,57mm (1: 87) = 920mm (prototype) - this diameter is exaclty used in every type of the freight-bogies: Y25,
http://www.drehgestelle.de/6/y25_t.html) on the bogies: Υ25 of ROCO, is excellent and smooth. They are more flexible bogies from the "heavy" ones with leaf-springs: MINDEN/SIEGEN of ROCO, i.e. Taems890 DB A.G.
In the last mentioned freight wagon, I will use Υ25 ones according to the prototype, or I will "open" them a little - just for the wheels to be flexible on any irregullarity of the track-interface 
, but I believe that the Υ25 ones are the exact for the DB A.G. Taems890. The DB version has the heavy ones (last pic of the prortotype).
Y25 - wheel-diameter
06.10.2013:
1. Assembly of already soldered / completed Brake-releaser / Lösezüge, WEINERT MODELLBAU.
2. Assembly of hooks underneath the coupling-hook, for the protection of the rest parts of the buffer-plank during movement of train, according to the prototype. Already cast bended hook out of 0,3mm - brass-wire was used, which was soldered at each one end with 0,3mm - brass-wire (WEINERT MODELLBAU), so as to be as to be fitted underneath the couplinmg-hook with super-glue.
3. Hand-painting of the assembled hook and brake-releaser.
It also needs:
1./ Screw-couplings from WEIMANN, Art. Nr.: 5091811022.
2./ High-powered buffers (Hochleistungspuffer) with buffer-plate - sixe: 450mm x 340mm, from WEIMANN, Art. Nr.: 507 18 21801.
3./ Airbrake hoses from WEINERT, Art. Nr.: 8293, not assembled yet. They will be assembled after the assembly of the screw-couplings.
I ALREADY HAVE THEM4./ Connection of the existing airbrake-system with the airbrake-hoses with 0,5mn - brass-wires, like I did in the, i.e. Ψ3 ΟΣΕ/CH, Eaos 106 DB, SNCF TA60.
5./ Change of the decals of the SBB CFF FFS, with ΟΣΕ/ΤΡΑΙΝΟΣΕ.
With more progress, I will post more pics.
Thanx
Dimitris
P.S. I also want to add that the "backs" above the buffer-plank are differnet than the prototype, but that is OK with me.
