Modern Steam Technology

The purpose of this page is to illustrate some of the items of technology often listed in the specification of modern steam locos but often about which little is generally known. Further items will be added as time and information becomes available. This is certainly NOT exhaustive at this point in time.....

Poissonnier Chassis Alignment

This system was considered, by Porta, to be the best system for the alignment of a locomotive chassis, better than many other methods including optical lining up.

The document presented is that send by M. Poissonnier to L.D. Porta in October 1952. Sadly in the intervening years page 28 has gone missing. However, its absence should not be a great loss to anyone who already understands the concepts.
