For railfans, much of the aura surround the Butte, Anaconda & Pacific (reporting marks, BAP) was its electrified operations,
which were in service for more than 50 years until diesels fully
replaced the motors. During those years, however, it was quite a sight
to see BA&P electrics mingling near Milwaukee Road Class EF-4
"Little Joes", as the CMStP&P interchanged with the road at three
different locations. From an operating standpoint the BA&P relied
almost exclusively on its primary commodity,
hauling copper ore from mines located near Butte to the smelters at
Anaconda. During the 1980s the smelters closed and the railroad was
purchased by an outside investment
group which renamed it as the Rarus Railway. The line continued to
operate under this name for many years until it was repurchased in the
2000s by Patriot Rail which returned it to its original name, the Butte,
Anaconda and Pacific Railway. Today, the BA&P continues to haul
copper products along with a variety of other freight.
The history of the Butte, Anaconda and Pacific Railway begins in 1893
when it was founded by the Anaconda Copper Mining Company.
Interestingly, at the time of the BA&P's chartering there was only
railroad serving Butte, and much of Montana, the Northern Pacific
Railway which was the first company to complete the transcontinental
link to Seattle from Chicago. While owned by the copper company the
BA&P essentially operated as a common-carrier system hauling general
freight and passengers along with its copper traffic. Its main line
from Butte to Anaconda (which actually roughly paralleled the NP's, and
later Milwaukee Road's main line) was 25.7 miles in length, according to
its timetable, and also later hosted a branch line from Anaconda to
Browns a distance of 6.2 miles.
For power the BA&P began services with traditional steam locomotives using mostly medium-sized power such as 2-8-0 Consolidations and 4-8-0 twelve wheelers. However, after 1910 the railroad decided to electrify much of its property. To do so it utilized a powerful 2400v direct current (DC) system, built in conjunction with General Electric and opened in 1912. Of note, the railroad during peak operations owned and operated a total of 135 miles of track, which included aside from the main line; yards, branches, spurs, and industrial trackage. Of this, 75 miles were electrified. It was GE who also furnished the railroad its motive power, small boxcab motors which began arriving on the property over the next few years, eventually reaching a total of 18 units.
After the Milwaukee Road arrived in Montana and opened its main line to Seattle, which occurred just a few years prior to the BA&P's electrification the railroad had three interchange points with four different Class Is; the Milwaukee Road, Northern Pacific, and Great Northern and Union Pacific at Silver Box (CMStP&P, NP), Butte (CMStP&P, GN, NP), and Rocker (CMStP&P, UP, NP). One other important point to note is that for a few years, after the Butte, Anaconda and Pacific Railway completed its electrification it featured a short stretch of interurban-like service on a small branch from near Anaconda to Opportunity. The purpose of this line was simply to haul miners to and from the work site although surprisingly it remained in use as late as 1951 when it was finally abandoned. General passenger services were, of course, never a particularly high volume of traffic for the BA&P. By the 1950s the service declined to the point that in 1955 the company ended operations altogether, from then on focusing solely on freight operations.
The 1950s also saw the decline of steam and electric services. In 1952 the remaining steamers were scrapped, replaced by Electro-Motive four-axle GP7s and GP9s. The boxcabs were also slowly retired although in 1957 the BA&P picked up two new GE motors, #201-202, which somewhat resembled early EMD Geeps. Sadly, however, these were used for only another ten years. In 1967 the electricity was turned off and the wires pulled down two years later in 1969. From that point forward the BA&P was fully dieselized. In the early 1980s the Anaconda Copper Mining Company closed its smelters which dealt a heavy blow to the railroad's traffic base. In 1985 the state of Montana acquired the line and subsequently resold it to a group of investors, which renamed it as the Rarus Railway in 1990.
Butte, Anaconda & Pacific Locomotive Roster
Acquired in 1972 from Tooele Valley Railway, sold to Anaconda Aluminum in 1981.
Purchased new in 1952 and 1953.
Purchased new in 1957.
Purchased new 1977-1978.
The Rarus Railway continued to operate under this name until 2007 when
it was acquired by the Patriot Rail Corporation, which as aforementioned
returned the property to its original name as the Butte, Anaconda and
Pacific Railway. Today, the BA&P operates its 26 mile main line as
well 37 additional miles of yard and industrial trackage. Its traffic
continues to be heavily copper-related including copper tailings,
impacted soils, copper concentrates, and slag according to Patriot Rail.
The railroad still connects with the BNSF Railway at Butte as well as
the BNSF and Union Pacific at Silver Bow.
