Comments

This wagon did not interest me particularly initially, but it was offered at a very inter­esting price for Brawa.

Wagon finely engraved. The metallic aspect of the walls is well rendered; that of the sliding roof curiously less well, with more visible metallic particles. Inserted parts: rail­ings, coupling handles, in metal. Roof steer­ing wheels, underframe braking equipment, in plastic.

The door manoeuvring inscriptions, very fine, in German, French and Italian, are perfectly readable with a magnifying glass.

The guard plates of the axle boxes are very thin. In fact, they are metallic (U-shaped parts), the axle boxes being — more or less — glued on. One has taken off. They are mounted with clearance, probably to ease the inscription in curve. The wheels, slightly browned, have a 0.8 mm flange and a diame­ter of 10.3 mm, which corresponds to 900 in reality. I don’t know if it’s right, but since the overall height is a bit low as well as the buffers, I have a doubt. However, as the brake shoes are close to the wheels, it will not be easy to replace them with larger ones.

Axle shaft dimensions : L = 23.3 ; ø = 1.5. Rather special!

A closer look at the inscriptions of the chas­sis shows me the phrase “Zulässiger größter Laufkreisdurchmesser 920 mm”, which means “Maximum authorized rolling circle di­ameter 920 mm”. I deduce that the new wheels should be 920 mm.

A bag of parts includes dummy couplings with and without shackle, and half brake hose couplings.

A historical notice is provided, in German and English.

History

Wagons built from 1968 in 1,100 units for the type B. They present both a sliding roof in two parts, like the SNCF Ts 1.01 (of German origin too), and sliding walls like the French EVS wagons.

Tare 13.6 t; maximum load 26.4 t.

The roof and sliding walls are raw aluminium alloy that gets dirty by taking a grey brownish hue.

The Tbis869 type A and type B wagons are distinguished by the manoeuvring of the roof: by levers accessible on a high bridge for the first one; by cranks accessible from the ground for the last one.
