For two reasons it's a topical time to add a note about the way keywords are used in this gallery. The first is that a long-standing issue with the Zenfolio search function was fixed not too long ago and the second is that I have been spending a lot of time updating them in the Saddleworth gallery. Keywords are helpful when searching for something by giving a standardised form of wording that is used for each relevant photograph. The keywords section on each page includes hyperlinks such that clicking on a keyword will lead to a gallery search for that word (or combination of words).
The keywords follow some standard rules but end up a little idiosyncratic as you have to develop your own rules - sometimes time tells you the rule wasn't quite right but it isn't practical to go back and change everything. It's useful to give an idea about the way keywords are assigned so you know how they can help you in a search. Keywords are normally assigned for registration, chassis, body, operator, previous operators and location:
This is always shown without the spaces as this gives a more effective text string for searching, for example "FBU827".
The chassis make and model are assigned separately, for example "AEC" and "Reliance". In some cases the top-level model variant is shown, for example "Titan PD1" and "Titan PD2" but sometimes the specific variant has to be used as there is no logical other way. With Bristol, for example, they hardly ever gave models a name and "RE" would be a useless search string as it occurs in too many words. Here I use the full designation, for example "RESL6G".
The make and model name are again used, but here model names are less common. I don't normally go for sub-variants, for example the different versions of Panorama Elite, but you will find exceptions! I have also not used the MCW "Orion", something I only realised lately and it was too late to correct. Where abbreviations are commonly used for coach builders I will use that as well - two common examples are "MCW" and "NCME". MCW may not always be used accurately as technically it referred to the sales organisation for Metro-Cammell and Weymann but I have used it more for Metro-Cammell products.
This is the most idiosyncratic part. I try to reflect the operator name in a way that will be searched for, but I realised that just putting "Oldham" would find all photographs taken in Oldham as well as Oldham Corporation buses, so I put "Oldham Corporation" and for municipalities I generally put the same, even for Manchester where Manchester City Transport was a later name. UDCs will have the name and UDC, for example "Pontypridd UDC" but sometimes in addition the initials like "PUDC". Other operators have the fleet name and where there are familiar abbreviations they are also used, for example "BMMO". "NWRCC" and "WWOC". PTEs have the full name and also initials (e.g. "WMPTE") except for SELNEC which appears on its own along with the division like "Southern" when appropriate.
This follows the same rule as for Operator but includes any operators who had operated the vehicle before the date of the photo. This includes examples that were ordered by one operator but were delivered to another (due to takeover or diversion). It is only ever retrospective and doesn't look into the future after the date of the photo.
This is more self-explanatory and will generally just be the place where the photograph is taken. Sometimes there is more than one name, to give a place and a more specific location. Three such examples are "Oldham" and "Mumps", "Delph" and "Carrcote" and also "Greenfield" and "Greenfield station"
It's complicated to explain but much simpler to use, remember that if you want more photos like one seen, pick the appropriate keyword(s) from those displayed. Remember also that I'm human and errors and omissions are more than likely!
