Dalman One-level Trucks: Part One


May 29, 1937, Kingston, Rhode Island, Bob's Photo

A preliminary note: this post covers only Dalman One-level trucks without Barber Lateral Motion Devices. There will be a "Part Two" that delves into that group. There is a table of known (to me) prototype users of this design at the end of this post.

The Dalman Two-level truck had a lesser known and lesser adopted sibling, the Dalman One-level. While not as distinctive as its sibling, the One-level was nevertheless unusual in appearance.

MILW 595775 had its Hutchins Dry Lading roof raised by seven inches and rides on Dalman One-level trucks, too! Jay Williams/Big Four Graphics

Why the post about this truck? Well, we are now fortunate to have a beautiful HO scale version of this truck, just in time to pair with my forthcoming Milwaukee 50' single sheathed auto cars. Plate C has released yet another fine rendition of a truck missing from the HO scale modelers lineup.

I am certain this list is not exhaustive. If you know of any omissions or errors, please leave a comment below and I will update the table. Thank you!

*There were several groups of MILW cars, including from the 714000-series of virtually identical single sheathed cars, that rode on a Symington truck that can best be described as a hybrid of the Dalman one- and two-level designs, without Barber lateral motion devices. It is not the same as Dalman design trucks

**There are photographic examples of Dalman one-level trucks in use on NH 58000- and 60000-series gondolas. Those are likely replacements or swaps made in the company shops
