One of the first things I did when I developed the concept of the Chesapeake, Wheeling and Erie Railroad was to establish a numbering system for the freight car fleet. Hopper cars would be in the 70,000 range, with earlier cars in the lower portion and more recent cars in the higher portion of the series. The chart below shows how various cars fit into the scheme.
Note the addition of cars in the 125,000 and 103,000 series. Once the Bowser 100 ton cars and the BLI H2A cars became available, I had to add expand the series to accommodated these cars. A quick check of the numbering series for the C&O's vast hopper car fleet revealed that cars were numbered in a variety of series. So adding the 103,000 and 125,000 series certainly seemed plausible.
As part of my renewed focus on building hopper cars for the layout, I took a tally of how many had been completed. There were just under 100 cars that had been painted and lettered for the home road. It occurred to me that I could memorialize a milestone by numbering the 100th car as XX100. And while I was at it, I may as well number the 99th car. So below are numbers 125100 and 125099 at Hollister Yard in North Pierce, WV.
In the picture below, 125100 is rolling east on the Sand Fork Shifter headed for one of the tipples along the Sand Fork Branch.
And in this last shot, we catch 125099 crossing White Oak Creek Trestle, having been loaded earlier in the day at Consolidated Coal Tipple #4 at the end of the Sand Fork Branch.
I sure hope it doesn't take as long to get to #'s 199 and 200 as it did to get to these two...
