The 33K gallon tank car decal sets were designed for the Walthers LPG tank car, which is based on a Union Tank Car prototype. This set features lettering introduced with the 1997 paint scheme along with a stylized "UTLX" and "THE TANK CAR PEOPLE" slogan introduced in 2004. As with all my UTLX decal sets the book "UTLX Markings 1970s to Present" by David Casdorph was a great source of information. This set, along with the other 1997 and 1984 era sets, required the creation of a font to properly depict the lettering.
