Hope you all are enjoying the season, and your special days. Here’s a happy little image:
Some Notes About Gauge in Our Database
To begin with, CSX.com’s railroad dictionary defines gauge as follows:
The distance between the heads of rails, measured at a point 5/8 inches below the top of the rail. Standard gage in the United States and Canada measures 4 ft. 8 1/2 inches.
https://www.csx.com/index.cfm/about-us/company-overview/railroad-dictionary/?i=G#:~:text=Gage%20(AKA%20Gauge),8%201%2F2%20inches.
The data in steamlocomotive.info’s database originated from a number of sources and there was little consistency in how this information was stored and expressed. We’ve just completed a project to rationalize this information. Here’s what has changed:
- Some locomotives were listed as “n.g.”, “n,g”, “ng” or “Narrow Gauge”. This does NOT fit the definition of gauge and only represents someone’s opinion that the gauge of the locomotive in question was narrower than some other locomotive’s gauge. This representation has been replaced with the word “Unknown”
- Some locomotives had this field left blank. These have been changed to “Unknown” as well.
- Locomotives which originated in countries using the metric system, have their gauge represented by a three or four digit number followed by the letters “mm”. Thus 760mm or 1000mm are examples. In some cases there was a space between the digits and the letters mm. These spaces have been removed.
- Locomotives which originated in countries using the Imperial System of measurements now have their gauge represented by a number followed by the quotation mark. Examples: 56.5″, 36″. These gauges were represented in a large number of ways, with and without the quotation mark. Three feet was changed to 36″, and so forth.
- Lastly, the Gauge field in the database contained some historical data for a few locomotives, thusly: “600m (regauged from 760mm). The parenthesized comments have been removed, and may be included for any locomotive by posting a note to that effect.
It is believed that the database, as to Gauge, is now consistent. The administrative interface for adding a new locomotive constrains the gauge field to the set of pre-defined gauges. If a gauge for a new locomotive is not represented in this list, the Editor may edit the locomotive’s information, creating the new gauge, and that new gauge will be incorporated into the system automatically, going forward.
I can almost hear the plaintive cries, though. “Woe! Woe! I don’t understand Imperial (or metric).” We’ve got a solution for that going forward too. We are going to add a configuration item that will let you choose Imperial or Metric and the field will be displayed in whichever measurement system you prefer. If you allow cookies, the choice you make will persist through any number of visits to the site. The cookie will contain a single word, either “metric” or “imperial” and no other information. I’ll put an announcement up on the front page as soon as it is available.

Another One Bites the Dust
Tiny Town Railroad 2-6-6 No. 12 “Mary Ross” in Morrison, Colorado shown below, in an image by Chris Guenzler has been removed from our database and website, as it is a steam outline locomotive powered by a 4 cylinder Lombardini diesel motor. It was constructed by the Uhrich Locomotive Works in Colorado. As cute as it is, it doesn’t fit our criteria for inclusion. If it had been an actual steam locomotive that was later dieselized, we’d include it. So, in memoriam:
Date of Photo
Some time ago, I added a field to the locomotive display page labeled ‘Date of Photo:’. For quite some time, the field always said Unknown. The field is circled in the image below:
A utility was written to scan the images in our system for Exif data containing the field Date/Time Original and that data was added to the record for each locomotive which had a photo containing the Date/Time Original information.
The process used to approve a photo submitted by a user was also modified, so that any future photos containing the time stamp described above will be listed this way on the website. I hope that you will find this interesting, or possibly even useful.
Abbreviations and Footnotes
For most of the world (in our website) the names of the railroads which match to locomotives contain abbreviations, lots of abbreviations. And to be quite honest most of those abbreviations were unfamiliar to me, and I assume that they were also unfamiliar to many site visitors. So I have sought out a solution to this problem. Consider the screen capture below:
This is the top of the locomotive display that anyone who clicks on a thumbnail image sees, but slightly changed. Please note that the two abbreviations used for this locomotive have superscripts after them, indicating the presence of a footnote. Whenever abbreviations appear in the name of the railroad(s) you’ll see this, and another thing will happen. A box will appear below the information shown for the locomotive, explaining the abbreviations. In this case, it looks like this:
A Small Fix
In my most recent posting I noted that I didn’t like the way that an image containing text was worded. That image was:
It struck me that it was awkwardly worded, and quite ungrammatical. So, to remove that irritant, I’ve replaced it with the following:
Whether this is any better, actually, I don’t know. But it doesn’t irritate me (much). So this version will stay for now. And of course, NOW I notice that I misspelled photograph in the new version. Blargh.
Most Common Complaints
Running, maintaining and updating steamlocomotive.info has been a fascinating obsession these last twenty (20!) years. The site came on the air in September of 2001 in a very primitive form. We had about 1400 locomotives in the database, and pictures of about 800 of them. Initially we included just the United States. Since that inauspicious beginning, we’ve expanded to include the whole world with the help of an enormous list of contributors.
Let us take a look at what is currently on the website:
Complaint: You list scrapped locomotives. Why? You shouldn’t!
Yes, we list scrapped locomotives. These are almost universally locomotives whose scrapping was reported AFTER we started this website. So they were listed at one time, because they existed. Rather than have them vanish magically when scrapped we chose to simply change the locomotive’s status to Scrapped and retain whatever information and photos we had for the locomotive. This has the charming advantage of preventing a particularly annoying question: “You don’t list locomotive XYZ that was at Left Overshoe, West Dakota. Why?” Well because it was scrapped.
So to put this in short form. We list scrapped locomotives because we think it is the best way to record the pool of locomotives that existed when we started this project.
If this truly annoys you, click on the Custom View button on the website’s front page, change Show Scrapped Locomotives to ‘No’ and click Submit. Voila! Your problem is gone. Curiously in the seven years since I implemented that feature, not one single user (other than me) has used. it.
Complaint: You Don’t Have a Picture of Locomotive XYZ!
You are undoubtedly correct. But we do have pictures of 13466 locomotives. We are deeply saddened that we don’t have a picture of your favorite locomotive. If you have a photo of the locomotive it is extremely easy to submit it. If you’ve seen the image below:
Simply click there and follow the instructions. Of course that assumes that you actually have a photo of it yourself. And believe it or not, after 20 years I just noticed how idiotic the content of the image above actually is. Grammatically incorrect. Just added this to my list of things to fix. Sigh.
Biggest Complaint: You Never Update Anything!
Umm. Okay. Here’s a summary of what got changed each month in 2021:
Well, okay. So I didn’t include August. Through July, we’ve made 3,444 changes to the database as summarized above. If you’d like more information than I’ve presented here, click the ‘Change Report’ button on the site’s front page.
All About Links To Other Sites
I think most site visitors are aware that some locomotives have a “Links” page providing links to other sites that have information about that particular locomotive. I am embarrassed to admit that, back in 2001 when this site was being created the liks pages were a bit of an afterthought.
I provided means for a site visitor to submit a link, and means for an editor to approve that submission. Though the Admin menu for Links had entries for Add, Edit and Delete, they were never written.
About three months ago, I took a long look at the site, what it could do and what it couldn’t. I used Google Analytics to delve into how visitors to the site used it, and what features were used most often. I was surprised to learn and the links we provide were clicked on an average of about 40 times a day, sitewide.
So I put it on my work list to improve the Admin interface so that our editors had tools to better maintain the database of links. And about 6 days ago, I dug into the problem. I was partly motivated by the discovery that there were a couple of “broken” links on the Milwaukee Road 261 page. It would have been easy enough to go into the database using a management tool and simply remove the defective entry, but that didn’t fit with my redesign philosophy. I’m trying to make the site completely maintainable by someone with now programming or database skills.
In any case, I went ahead and wrote the “Delete Link” functionality for our editors, and it worked nicely. Somewhere along the way, I began to wonder just how many broken links there are in database. I imagined that it would be an annoying experience for a site visitor to click on a link and end up going nowhere.
I wrote a tool to go through the database and attempt to read each and every link in the database, and record what happened. The program attempts to go to the website in the link and records what happens when it does. The following table shows the results: 3525 of the 4347 links in our database were definitely valid.
| Error Code | Meaning | Count |
| 200 | Page Successfully Retrieved | 3,525 |
| 0 | DNS Resolver Failure | 373 |
| 400 | Bad Request | 1 |
| 401 | Unauthorized | 1 |
| 403 | Forbidden Error | 23 |
| 404 | Page Not Found | 367 |
| 408 | Request Timeout Error | 42 |
| 410 | Gone | 3 |
| 500 | Internal Server Error | 5 |
| 502 | Bad Gateway | 3 |
| 503 | Service Unavailable (Temporary) | 2 |
I could probably bore you witless by explaining the various error codes, but insteal I will summarize: if the code isn’t 200, it didn’t work. I will be pruning the dead sites/links from the database today.
Hopefully this will make the site more useful and usable, and perhaps a bit less annoying.
Geographic Browser Update
The geographic browser function I’ve talked about elsewhere is coming along nicely. Based on visitor feedback, I want to provide additional information about the markers used on the maps. The red and green markers are pretty much self explanatory, but the blue ones have caused some confusion.
First of all, it is important to note that the markers on the geographic browser maps do not reflect a precise location for a locomotive. They are intended to show general locale, like city, state or village. If you zoom in far enough, you may notice this. The blue markers, designating multiple locomotives were added to reduce clutter on the display and to provide more information. Let’s consider Galveston, TX. The blue marker there replaces three green markers, all of which were in precisely the same location. Without the blue marker, you’d only see the information for whichever locomotive’s marker ended up on the top of the pile. Instead we have a blue marker, which, when clicked, gives you the following display:
Pretty simple, really. The top line of the little pop up window identifies the location within the city, the second line lists the city, state and country. What apparently confused some folk visiting the site is when you have a blue marker in a city like San Antonio, where there are multiple locations within the city which have locomotives. Then you get a display that looks like this:
In this case, the top line(s) look much different. Each of the places, separated by the / character have locomotives, all within the city of San Antonio.
These information windows are generated by a computer program and stored pending someone clicking on the appropriate marker. The program isn’t particularly bright, and doesn’t make value judgments about what it includes. If, during data entry those many years ago, I listed one locomotive as being at the Harlequin Railroad in Left Overshoe, Nebraska and another at the Harlequin Railway in Left Overshoe, Nebraska then the program would list both locations on the top line.
Many more features are planned (and being worked on). One will make the locomotives in those pop up windows clickable to get a screen with everything we know about the locomotive.
Website Updates 08-02-2020
Still working on the Geographic Browser. Over the last two days I’ve improved the regional/state/province borders for Spain, Germany and Canada. This was somewhat time consuming, but they certainly look nicer.
Secondarily I’ve continued to work on the Admin interface tools for the Geographic Browser. I’m getting close to finishing the first (of many).
