Ditch Lights (Trains)

For the younger generation ditch lights on locomotives seem quite common although such a safety feature has only been in use since the mid-1990s.  Prior to that time, as many of us remember, a locomotive was equipped only with its center headlight on a short or long hood (or in the case of a steamer, on the smokebox).  The light became a requirement by the Federal Railroad Administration (FRA) to improve visual sight lines of oncoming trains and locomotives by not only adding an additional lights to the head-end but also those that flashed.  Today, every locomotive in regular freight service that passes through a grade-crossing must have operating ditch lights or else face stiff penalties from the FRA.  

However, historic equipment built before a certain date do have more leeway in this regard, notably steam locomotives.  Also of note are rules regarding recently-built steam locomotives, which are somewhat unclear at this time.  Steam Into History's 4-4-0 #17, manufactured by the Kloke Locomotive Works in 2013, does not feature such equipment.  However, The T-1 Trust's attempts to build a new Pennsylvania Railroad 4-4-4-4 "Duplex Drive" may require ditch lights due to its size and length.

Prior to the widespread use of ditch lights during the 1990s railroads had always relied on a single or double-bulb headlight for illumination (basically however the manufacturer designed and styled the casing); for diesels these were normally situated high at the ends of each hood or centered on the smokebox of steam locomotives (some steamers also had a pilot light on the rear tender that offered illumination for crewmen at night).  When diesels began carrying low, short hoods the headlight was re-situated and centered near the top of this hood not unlike on a steamer.  However it was placed on locomotives back then the light always provided sufficient illumination and it remained on nearly around the clock during the diesel era, except when the locomotive was not in service.

Interestingly, the railroad industry did utilize special lights to increase visibility years before the ditch light became mandatory.  During the late 1930s Jerry Kennelly, a firefighter from Chicago, designed an oscillating light to catch the attention of motorists and bystanders to stay clear of an approaching train.  What was known as the Mars Light, manufactured by his company the Mars Signal Light Company, the device normally consisted of two bulbs (either of the same or different color) rotating in a figure-eight pattern.  The device, which was also applied to late era steam locomotives on some railroads, was normally found only in passenger service since people were trackside more often.  Over the years Mars, and its competitors, produced several different variants of safety lights which had all but fell out of favor by the 1980s due to increased maintenance costs.

Through the early 1990s the design and function of locomotive's headlights changed little save for the FRA's requirements of candela output (a term that describes a unit of luminous intensity).  In an effort to further improve safety for both the train crew and those trackside (motorists, pedestrians, or even railroad workers) the FRA finally made a change to the age-old practice of headlight usage (a device which had really been given little thought over the years by most except for the workers that maintained them).  On March 6, 1996 the federal agency on safety and oversight of the railroad industry released a new rule stating that locomotives operating at speeds of greater than 20 mph that regularly passed through public grade crossings would be required to use ditch lights.

According to the FRA these auxiliary lights, which must burn at 200,000 candela, would be situated on the front and rear pilots of a locomotive to form a triangle and be placed at least 36 inches above the rail head; they would also be located either 36 inches or 60 inches apart from one another depending on the distance from the primary headlight.  In one final added measure of safety the lights would be required to flash alternately "at least 40 intervals per minute and no more than 180 intervals per minute."  The FRA's requirements for the new lights were quite strict stating that they must be activated any time a locomotive was in motion and if a bulb was burned out or not functioning it must be replaced as soon as possible.  Railroads were given a little over a year to implement the lights on all locomotives and a date of December 31, 1997 was set as the time in which to do so.

There were few exceptions with the new rule but one notable exemption stated that any locomotive manufactured prior to December 31, 1948 and not used in regular commuter or intercity passenger service would be deemed historic equipment and thus not required to be equipped with the lights.  As such, virtually no steam locomotives operating today carry the equipment and most classic diesels found pulling excursions also do not operate the lights.  However, you can find them in use on early Electro-Motive cab models either operated by Class Is (for their business trains) or a few tourist lines.  Of note is the Norfolk Southern's fleet of restored F units pulling its Office Car Special (OCS).  When the locomotives were overhauled shop forces countersunk the ditch lights into the nose giving them a very nice, clean, and finished appearance.

Depending on your interest level of locomotives, and diesels in particular, a few books on the subject which may be of interest include Mike Schafer’s Vintage Diesel Locomotives and J. Parker Lamb's Evolution Of The American Diesel Locomotive.  As the title suggests Mr. Lamb's book provides a general history of the diesel through the years.  In the case of Mr. Schafer's book, it is not particularly long (less than 100 pages) but it is nevertheless pretty interesting!  His title provides a quick look at several classic diesel models from early Electro-Motive products to venerable designs by Baldwin, Fairbanks Morse, and the American Locomotive (Alco).

Researching Rights-Of-Way

A popular pastime for many is studying and/or exploring abandoned rights-of-way.  Today, there are tens of thousands of miles scattered throughout the country.  Many were pulled up in the 1970's and 1980's although others were removed long before that.  If you are researching active or abandoned corridors you might want to check out the United States Geological Survey's (USGS) Historical Topographic Map Explorer.  It is an excellent resource with thousands of historic maps on file throughout the country.  Just type in a town or city and click on the timeline of maps at the bottom of the page!

Studying Diesels

You will be hard pressed at finding a better online resource regarding diesel locomotives than Craig Rutherford's TheDieselShop.us.  The website contains everything from historic (fallen flags) to contemporary (Class I's, regionals, short lines, and even some museums/tourist lines) rosters, locomotive production information, technical data, all notable models cataloged by the five major builders (American Locomotive, Electro-Motive, General Electric, Fairbanks-Morse, and Baldwin), and much more.  A highly recommended database!

Electro-Motive Database

In 1998 a gentleman by the name of Andre Kristopans put together a web page highlighting virtually every unit every out-shopped by General Motors' Electro-Motive Division.  Alas, in 2013 the site closed by thankfully Don Strack rescued the data and transferred it over to his UtahRails.net site (another fine resource).  If you are researching anything EMD related please visit this page first.  The information includes original numbers, serials, and order numbers.
