The Texas State Railroad in Rusk, Texas, is apparently doing a property cleanup, and one of the pieces of equipment included on page 5 of their disposition list is the car body shown above (2019 photo by Mitch Goldman from here), Cincinnati & Lake Erie 646. Car 646 has led a tough life: built by Cincinnati in 1930 as part of the 635-649 series of modern freight motors, it was one of seven sold to American Aggregates for conversion into a diesel locomotive. This one was modified less than some - it was shortened neither in height nor length, as some of the AmAg conversions were - but it did lose its original roof profile at either end and received a number of other changes. Anyway, at some point - I think in the late 1970s, but I'm not sure - it was acquired by the Indiana Railway Museum in French Lick. They sold it in 1999 to the group restoring Northern Texas Traction 25 in Fort Worth, which salvaged the trucks off 646 and then conveyed the body to TSRR for use as a storage container at their Rusk shop site. I believe it's been in Rusk for something over 20 years.
The car is in rough shape, even for a body, so it's probably a long shot that it will find a new home. But time will tell. The fact that the disposition list is titled "TSRR disposition-scrap list" is an indication of what's likely to transpire if a taker isn't found. By the way, more history of the 1930 C&LE freight motors can be found here. Thanks to Jeron Glander for pointing out the disposition list with 646 on it.
While I'm on the subject of the TSRR, I still haven't gotten a satisfactory answer to my question about what happened to Texas Electric 605 and 613, the two interurban freight trailers that once resided on the ground in Rusk just a few steps away from C&LE 646. They've disappeared from Google aerial and Street View photos, but I don't know whether they were dismantled or just relocated somewhere else, either on the grounds or further afield. The fact that they're not on the current disposition list also seems to suggest that they may no longer be on the property. Anyone know for certain whether 605 and 613 are still there at TSRR?
