Think the English translation (!) is 'lozenge-shaped passenger cars', i.e. the octagonal-shaped UTDC/Bombardier bilevel commuter cars originally operated by GO Transit and now operated by several agencies. Their trucks might work, as they are inboard-bearing types. The IB-types from the Atlas Comet cars might also work. Other than that, if you wanted the exact trucks, they'd have to be custom-made in zinc. Possible but expensive.
