A Great Reference List for looking up steam locomotive rolling stock and it is a credit to you for all your hard work. I, myself use the Ramsay's British Model Trains Catalogue (RBMT) compiled by Pat Hammond and edited by Phil Parker, which is published by BRM (British Railway Modeller). This is currently (as the date of post) on its 9th Edition in a two-volume set Vol 1 A-G and Vol 2 H-Z. It Covers many manufacturers past and present and also caters for and as a price guide too at the time of printing towards there current value in say an auction. I have purchased this catalogue since its first issue and use it to update my own rolling stock listings if I am missing any details. I try to keep it simple with columns for the year of release, wheel arrangements, class, loco description, company, loco #, and cat # it is issued under by the manufacturers, e.g. 2014 4-6-2 A4 (LE-TGG) Dwight D Eisenhower BR 60008 R3255 2004 Bo-Bo 170/2 DMU 2 Car Turbostar Anglia 170271 32-453 2011 Co-Co D16/1 Brunswick Green BR 10001 10001HAP 2019 1CoCo1 D16/2 Atlantic Coast Express LE BR 10203 K2703A 2019 Bo-Bo 24 Experiment (ex 24091) BR RTC 97201 SLW2406 The same basic layout of spaced columned details goes into my other list of wagons and coaches, using the same abbreviations for limited editions (LE), weathered (W), sets like The Great Gathering/Goodbye (TGG), and train sets (TS) etc. As for items on pre-order they are highlighted on my listings in a Red Font liked the 2019 Class 24 SLW2406 (as above) from Suttons Locomotive Works would be typed onto the list. Any missing info in the fields is left blank until the details are found out, especially for purchased unboxed items. That is when the RBMT catalogue comes in handy for me to update my own private collection of rolling stock from Hornby, Bachmann, Dapol, Suttons Locomotive Works, Rail Exclusives, Kernow, Graham Farish, Model Power and Murphys Models etc.
