2nd-class (Open-room/compartment) USI car (B4t5½) (ex-A4t4), diagrammed on TER 96501 (Lyon Perrache-Genève Cornavin).
This is one of the 2 end-saloons (22 seats each).
As B4t5½t cars were among the last A4t4 cars to be declassified (mid-80s), their saloons feature seats similar to those of declassified TEE cars (Inox and Grand Confort), rather than B10t, older-style seats, as was conversely the case on B4t4 cars (declassified earlier, now all withdrawn).
This 2nd-class saloon is identical to that of dual-class A2t2B2t3 cars.
