Measurements of extrusions used in the fabrication of half-length APT prototype trailer-car roof section (described in IMSD 57) (IM-SD-058)

1. It is proposed to build a pre-production run of eleven APT trailer cars using full-length (i.e. 21m) extrusions. These extrusions, which are to be produced by Alusuisse, will form the outer skin, and will incorporate integral longitudinal internal stringers. In order to assess the feasibility of this form of...
