Re: 318's tender is 345's tender (and 340) {tender sluts}

Good research. But of course all of this assumes the Rio Grande's world began in the 1930s and when you are talking about which engine has which 'original' tender it really becomes a stretch.

I like the "tender sluts" moniker because that is definitely what the C-class engines were. All of these engines had tenders like the one casey calls 340's original tender, with the flared tops. The raised sided tenders like the 345 tender (which was larger and allowed whatever engine was working the Ouray branch to make it over the line after the Cow Creek tank burned) were all later additions from the turn of the 19th/20th Century and later.

So unless the tender looks like this:

we really can't say it's any engine's "original."
