Re: NG interchange

Regarding Interchange;
Re: Tank car interchange,
The COLX-CONX cars seemed to move around. there are waybills and other papers showing COLX 19 on both the C&S at Morrison and on the RGS. Colx 14 was built by the D&RG and ended up on the C&S at Leadville. CONX 35 was built in Alamosa and was photographed on the C&S in variious locations.
The Std Chemical cars appear to have been constructed by the C&S.
RE other Cars:
There are several waybills and some Photographs showing a mix of D&RG and C&S equipment on the Isolated C&S Romley Branch in the late teens and early 20's. The Leadville Mineral Belt RR regularly hauled both narrow grauge and standard gauge equipment from a number of lines using narrow gauge C&S Locomotives. The type and gauge of car seems to be a function of where the concentrates were headed. Narrow gauge C&S cars were sent to Salida via the D&RG.
The C&NW leased a D&RG class 56 Locomotive long enough to wreck it in the teen's.
Refering to Std Gauge cars on narrow gauge trucks
There is a series of Photos in The DSP&P Pictorial supplement and in the Rrobb Vol VIII of a C&S Standard Gauge car wrecked in Platte Canyon.
On the RGS:
Somehow there were Standard Gauge Box Car bodies used as Sheds at Vance Jct, Rico, and Ute Jct to name 3 locations.
During the mid to late forties there were UTLX cars changed back and forth from Std to Narrow Gauge each year.
