Number of Images on this Page = 1
The catalog is restricted to photographs where either I own the copyright, or permission has been given to include photographs here. Permission is given to copy any these images for personal or research use, but not for republishing, commercial gain or profit without written permission from me or the original copyright owner. I would appreciate hearing how you find these images useful.
G'day. This site started out as a way of cataloging my numerous railway pictures, which I first starting building up as a set of root window backgrounds. That was back in 1992, before the web. But once I became aware of the web (in 1994), I realised that a web page would not only allow me to peruse my catalog easily, but might also prove useful to others.
This site first went on-line in the week starting 3 Jul 1994, and I claim it as one of the first railway web pages! Proof of this lies in the school's server log pages, originally at http://www.csse.monash.edu.au/usage/cs/1994/week6.html , under "10 items accessed most ... /image_lib/trains 96". How about that for industrial archaeology? Currently (Dec 2016) the csse server is broken. But I have kept a copy of the relevant page, see School Server Usage Jul 1994. Look for the line that says "/image_lib/trains 96", which was my first trains web page.
Anyway, I hope you enjoy these pages. Many people have written to me to say they have enjoyed them, and you are welcome to drop me a note with your comments.
Supporting software for these pages has been redesigned.
One of the first things to be rebuilt was the full size image viewing routine. This previously had a great deal of HTML hard-coded into it, with the consequence that it was rather static, and did not keep up with other changes in my web pages. It now works in a similar way to all the XML pages, except that in this case, the XML page is generated on the fly, according to the image selected. The headers and footers thus reflect all the headers and footers in other pages. In particular, the inability of Microsoft's Internet Explorer to access these images has been circumvented.
Allied to that, the rankings page software has been reconstructed using a similar principle. It should be a more seamless transition to move between page views, detailed views, and ranking views.
Plans have been announced to remove the domain name www.csse.monash.edu.au, and all the pages under it. This will probably not happen for a while yet, but in the meantime, I have setup a new server (belonging to me, rather than the university) which will mirror all the railway photograph material for the foreseeable future. It is suggested that you start changing those bookmarks to:
(20170110) Well, that was a while ago. While the website www.csse.monash.edu.au has not actually disappeared, it has not been well, either, largely due to the obsolete equipment upon which it ran. Its recent death has been exaggerated, however, and new servers are currently being installed. So it should hang around for a few years yet. CAVEAT: The server does rely upon some fairly sophisticated software, which is yet to be brought up to date, so you should still use the other servers in preference. An interim server, users.monash.edu.au, is working in its place (with many redirections from its links). ajh.co/~ajh/trains and ajh.id.au/~ajh/trains are alternative links you can use as well as the preferred one above (ajhurst.org)
This page describes the extensive collection of railway images maintained at Computer Science, Monash University. For my other reciprocal railway links, see my Railway Links Page . If you have a railway page, and you'd like to swap links with me, just drop me an email note, and I'll add you in!
The numbering scheme used for the images themselves is relatively straightforward, and provides the basis for referencing all images and their descriptions. Where there is only one locomotive in the scene, its class/road number is used as the title. Multiple images of the same loco are reflected in a "-1", "-2", etc., suffix.
Where there is more than one locomotive in the scene, and the locomotives are coupled together, the road numbers are appended in the form "leading+trailing+.." as appropriate, again with a "-1" suffix to distinguish multiple images. If the locomotives are on separate tracks, the notation "loco=loco-1" is used. Multiple parallel running, with multiple coupled locos is handled by "loco+loco=loco-1" and so on.
Occasionally, where many locomotives appear in a scene, only the main ones may be identified (such as at roundhouses, etc.).
Where the railway scene does not specifically contain locos, it is labelled on a more ad-hoc basis, using the content as eponomously as possible.
Please mail ajh at ajhurst dot org if you enjoyed this archive, or if you have any comments or complaints!
Whether you are visiting for the first time, or revisiting, you will probably find the Recently Added Images page useful to see how things are progressing with these pages. I add things as I get time, and this page gives you a quick overview of what has changed of late.
I currently also have a rather large backlog of photos to put up, and while I am always most pleased to hear from new correspondents, I would ask you to note that if you send my photos for inclusion in these pages, there may be some delay in placing them online.
In an ongoing project like this, managing the large amount of information that is continually changing can rapidly become intractable. Hence I recognized quite early on that some sort of management system was imperative. Here are the various approaches that have been used:
Each image has its own description XML file. The main pages are defined as XML documents called index.xml that "include" the description files. Such files are then translated directly to the corresponding HTML page using an XSLT script. The shunting yards, or navigation bars at the head of each page are generated by a series of separate xml scripts, such as Central.xml.
Requests for files from the server can either be to the base XML file, or the derived HTML file. In both cases, a .htaccess file gives the server additional information on how to render the file.
For an XML file, there is a handler index.py that is invoked, and it is passed a parameter string indicating the XSLT stylesheet to be used for transforming the document into HTML, which is then delivered to the client. Dynamic data (such as file modification times) are delivered to the XSLT script at this point.
For an HTML file, if the file exists, it is retrieved and returned. This is a transition phenomenon only, where the HTML file is left over from the previous (static) method of rendering (see above section). Where the HTML file has been replaced by the XML file however, an Error 404 is generated (since the HTML file does not exist), and this is captured by the handler. The corresponding XML file is retrieved, the stylesheet name recovered from the nearest upward .htaccess file, and the process of the previous paragraph completed. All without any obvious action observed by the user.
Given any image reference (e.g., Gerogery-1) and its directory (e.g., misc), all the information required to present this image can be constructed from them, relative to the user home directory on the server, viz.:
A taxonomy of railway subjects is not straightforward. I have taken the approach of cataloguing by attribute of ownership, although the epoch is not necessarily consistent. Thus for example, Puffing Billy has a separate section, although most of the stock was originally built by the Victorian Railways. Visits by rolling stock to other systems further confuse this, especially where multiple items of different ownership are involved. Hopefully no one will be too confused by the approach taken. Of course, the author will happily entertain any debate upon the subject!
There is a dynamic ranking process that uses access to the full images as a voting mechanism. This does not use the web log files, but only records those images accessed by clicking on the thumbnails. See the Vox Pops page for more information, or clink here .
There is a new directory called "themes" containing themed photographs. These are photographs already in the album, but linked by a common theme. See Night Photographs for an example.
