Locomotive Notes
*Loco_Ja1243 was passed into service on 28 February 1947. Official trials commenced 4 March 1947
*Loco_Ka957 will probably be the first to be converted to oil burning at [[Otahuhu Workshops]]
*[[Mosgiel]] turntable was out of use for a while in mid March 1947 resulting in a lot of tender first running
**Loco_Ww680 was pressed into service straight out of [[Hillside Workshops|Hillside]] following an overhaul , it being some 20 years since these loco's worked this service.

Locomotive Boiler Numbering  by Mr. M. Botten
* A new scheme introduced in 1925 say all new stationary boilers numbered from 1 upwards and Locomotive boilers starting from 351 which went into Loco_D130
*The highest number so far was built at [[Hutt Workshops|Hutt]] and is is Boiler_424 fitted to Loco_K902
*The boilers for the new Ja_class_locos being built at [[Hillside Workshops|Hillside]] use the range 1389 up (to 1202?)
*The boilers for the K_class_loco's run from 1203 - 1232
*The boilers for the Ka_class_loco's run from 1265 - 1299 but 1293 and 1294 not in service yet as they are for loco_Ka958 and Loco_Ka959
*The boilers for the Kb_class_loco's run from 1300 - 1305
*The boilers for the J _class_loco's run from 1306 - 1345
*Boiler_1368 - 1371 are spares for Wf_class_loco's (superheated)
*Boiler_1377 - 1382 were built as spares for Ww_class_loco's (superheated) with 1Boiler_377 fitted to loco_Ww645 in August 1945 and Boiler_1379 fitted to Loco_Ww494 in February 1946
*Old Loco boilers reused as stationary boilers retained their old number
*Interestingly, The boiler fitted to Loco_K93 at Addington in 1903 became Boiler_363 after 1925, used as a washout boiler at Paekakariki from 3 December 1926 and was still at Hutt in 1946. Since dumped.
*Boiler_1024 seems to be the most swapped boiler Fitted to Loco_Ab806 in 1925, removed in 2/1930, fitted to Loco_611 in 12/1936, removed 11/1937, fitted to Loco_Ab778 in 1/1938, removed in 11/1939, fitted to Loco_Ab810 in 2/1940, removed in 7/1944, fitted to Loco_Ab719 in 2/1945.
