This page contains notes on the terms used in Locopage.

I should note that I can not claim that Locopage is 100% accurate simply due to the large amount of information on the site, and also the fact that I do it as a hobby. Therefore, if you do find mistakes, please don't hesitate to contact me, my email address is below.

I have just completed a design change to affect those locos sold from one operator to another, and also rebuilds; such that the complete history of these locos will all be on the page for the original class; there won't be a continuing series of pages, one for each new operator.

Photographer: I have removed email addresses from individual class pages as an anti-spam measure, check the Photo Gallery page for a complete list of photographer's email addresses.
Number in class: The total number of locomotives in the class. For a list of locos currently in service, please see the Fleetlist page.
Length: This is intended to be the length over couplers.
Power: The figure given for the "Power" value is intended to be engine (gross/total), and not traction power; if you can correct this, could you e-mail me please. Note that for several loco classes, particularly the earlier classes, the figures are still the traction power (because I do not know what the gross power is).
Tractive effort: This is the "pulling" power of the locomotive. The first figure is the starting tractive effort, the second continuous. Continuous tractive effort is usually at around 10-20 km/h. Tractive effort is inversely proportional to the speed.
For those interested, 1 N (Newton) is equal to the force required to accelerate a mass of 1 kilogram 1 metre per second per second.
Speed: This is the maximum speed (first figure) that the locomotive can reach, and the speed at continuous tractive effort (second figure); in normal operations (particularly for freight haulage) the actual speed can be a lot less.

Names: I have only listed the "official" names given to locomotives. Some locomotives that have been acquired by preservation groups have been given names by these groups; I have (generally) not listed these names.
Preserved: It is well worth noting that this category covers a wide range. Most preserved locomotives are with museums or preservation groups, while a few are on static display. Of those locomotives with museums and preservation groups, the range is of those in operational condition (and do mainline running), all the way to those that just sit and rust away (there is one group in particular here that comes to mind). I have indicated in the main table on locomotives which preserved locomotives are in operational condition (that I know of). Any amendments would be welcome. I have also set up a Preserved Locomotives page listing all preserved locomotives included on Locopage.

Dates: These now cover entry-into-service dates only, as keeping the withdrawl and scrapping dates updated has become too great a workload. I have placed an "?" where a particular date is unknown.
In service dates: some of these are delivery dates or dates of trials. Generally, the greatest difference would only be about one month anyway; in some cases it may be a few months. If there is a big difference, could you please let me know. For locos that have been transferred, "---" in this column indicates that they are not (yet) operational, or being used for spares.
Comments: This indicates whether a locomotive is scrapped, preserved, sold, rebuilt, or whatever else. A blank entry indicates that the loco is in service or stored. I won't always be updating details on loco scrappings in the future, due to the workload.
Note that the information for withdrawl and scrapping (and for operational locomotives) can be readily found from sources such as Motive Power's "Departure Road" section; Railway Digest's "Locoshed Express" section; email lists such as LocoShed and Ausloco, and Railpage's Forums. See the Links page for links to the relevant websites.

Colours of pages: I now have a Cascading Style Sheet - locopage.css - controlling the text, background, and hyperlink colours for all of the web pages on Locopage. The colours are either the colour name or hexadecimal (red-green-blue) format. This makes it much easier when making changes, etc. If you have any comments on the page colours (readability), please pass them on.
Details are as follows:
* "color" = text colour
* "background-color" = background (page) colour
* "A:link" = colour of hyperlinks that have not been visited
* "A:visited" = colour of hyperlinks that have been visited
* "A:active" = colour of hyperlink currently selected by the mouse
* "td" = text colour in a table
I have also included the names of directories and filenames; note that these are however uppercase in locopage.css whereas the actual directories and filenames are lowercase.

Hopefully, the rest of the information should be self-explanatory - please let me know if it isn't.

A downloadable database is also available

You can download a database of the information (MS Access, 350kB zipped, 5MB unzipped) if you wish. This has more complete information than this website (in terms of tech specs and fleet details), and is updated quarterly, along with the major updates for Locopage. The Zip file also contain a guide to the information (Adobe PDF).
