Just for the record. This set of photos showing the replacement of the articulation pin in a GG1 came across a Facebook feed. Perhaps these may one day provide clues to a future group looking to move a GG1 in pieces, be it on flat cars by truck (ie in three pieces, two sets of running gear and the body).

Very interesting collection of photos at that site. Here is one of a VERY LARGE metal planer;

https://digital.hagley.org/PRR_09958?so ... fset%5D=16

A metal planer is a large metal working machine where the work-piece (ie a gg1 frame) was mounted to a table that moved linearly "back and forth" past a metal cutting tool. Very interesting (and large machines). To finish a flat surface on a large 50 foot casting it would require a 100 foot planer..

Imagine running a wood plane over a 50 foot beam and getting it flat enough for the intended purpose.

It looks like the GG1 frame is setup in the metal planer to finish machine the inside/outside surfaces of the axle bearing boxes ?

Great photos, very interesting details.

Cheers, Kevin
