Cartazzi axle on LNER Peppercorn Class A1 60163 Tornado

A Cartazzi axle is a design of leading or trailing wheel support[1][2][3] used worldwide.[4][5][6][7][8] The design was used extensively on the former LNER's Pacific steam locomotives and named after its inventor F.J. Cartazzi,[9] formerly of the Great Northern Railway. It should not be confused with a pony truck as it does not pivot at all.[8] The axle does, however, have sideways play built in to accommodate tight curves. Cartazzi's design causes the weight of the locomotive to exert a self-centring action on the trailing wheels.[10]

The Cartazzi design was also sometimes applied to driving wheel axles on longer wheelbase locomotives.[11]

Modelling

On small scale models the trailing wheels of Cartazzi-axled locomotives are often flangeless to allow negotiation of tighter, non-prototypical curves, or the Cartazzi axle has been replaced with a pony truck for the same reason.
