Here is a photo of a Duluth Missabe and Northern box car carrying bulk cement and being unloaded. This was for the building of a new ore dock in 1916. There was a cement plant nearby where the car was

A few comments on this issue: 1. It is important to determine what railroad and the location you are modeling. There was a large difference in the number and owners of tank cars that traveled over the

I agree with Eric. Note that they are not uniformly spaced as they would be on a ventilated door. Likely for hauling coal. Cyril Durrenberger --------------------------------------------

Ray points out many issues. The equipment used on the railroads changed radically during this time period. Larger locomotives, steel passenger cars became the norm and there were major modifications i

Please sign you name to posts. You might also look at the yahoo group 1914 - 1940 RRing that deals with the time period of interest to you. There is much information and many of us will be happy to as

Another important part of any answer to this question is the time period of interest and the role of private owner cars. Without a sense of the time period it is not really possible to provide an answ

This is a common design used by the Union Tank Line from the 1880's until the after 1910. There were other tank cars built with a similar design, but with differences in details such as truss rods, wa

I attached a copy of the 1922 and 1927 listing in a previous email. Maybe they were stripped by the site. Cyril Durrenberger --------------------------------------------

One other comment on the content of the iron ore that was received from boats on the Great Lakes. Often the iron ore from different mines was combined in the boat to obtain the composition that the re

There could be many responses to your question. You indicated that 1957 was the era of interest. The first question that you need to answer is where did the ore come from and where was it mined. Was i
