The Cars That Went to Mexico

Just got the December Trains and it reviews a book by the above title, out from Railroad Books, Brooklyn, NY. Review says it covers sleepers, diners & lounges with a 2nd book coming to cover coaches & head end cars. It is claimed to have rosters, etc.

Anybody seen this yet and, if so, does it cover narrow ga cars? Like all the sleepers that went to Mexico at the turn of the 20th century or the Gunnison, Salida & Chair 403 from the Grande that went south in '42? Does it have more info than the CRA #25. (Like, for example, final dispositions?) Inquiring minds want to know.
