In 1898 the W.A.G.R. took over the stock of the Great Southern Railway. Many of the G.S.R. wagons were built on a standard 14'-0" long underframe, as were these high-sided wagons. They were unique in having gable ends and ridgepoles although in many cases the ridgepoles were removed. The same design were also used by the M.R.W.A. as their class A. The original GSR numbers and the class letter of this group are not known. It is believed that the original W.A.G.R. number sequence for these wagons was 4201-4240 and 4266-4315. In the 1900 renumbering 4229 was listed as a J class tanker and 4232 is missing. Number 4276 was rebuilt into an F class louvre van at about the same time (1900/01). Before 1906, number 4236 was also out of service.	Chidlow's Well station, just before 1900. The ex GSR wagons have WAGR numbers (from 1896) but not the post 1900 classes (class I in the photo not G).

It is known that in 1910 the following wagons retained their ridgepoles: 4201, 4204-9, 4211, 4218, 4219, 4221, 4222, 4224-7, 4231, 4237-9, 4240, 4266, 4270, 4272, 4274, 4277-4284, 4286, 4288, 4290-2, 4294-9, 4305, 4308.
This partial image at right, blown up from from State Library of WA 154005PD, shows G4224 at Fremantle still with its ridgepole in about 1911.

I find it hard to believe that one of these wagons lasted until 1970 and I am a bit dubious about the other late survivors but that is what the record cards suggest! The late survivors could possibly be standard N.Z.R. type G's which had somehow acquired numbers in this series. This is possible because of the sale and repurchase of wagons to contractors. The diagram below is the WAGR outline diagram for the class.
