The L-40 log cars were SP 42' skeleton logging cars built in the 1930's and in service until the late 60's. I am aware of the great pictures of these cars in Tony Thompson's SP Freight Cars Vol 3. I also have three pictures of the L-40-2 cars in service in the late 1960s.
Are there other pictures around? I am particularly interested in drawings and measurements of the L-40 cars in the 1-5 series. Any help in this research would be of real value, and much appreciated.
Has anyone explored the Stanford University Special Collections Box on these cars [M1010 RG3 Box 15] before I spend time and effort [from the UK] trying to investigate this material?
