It was used in the pageant (at the NY Fair during 1939-40) to represent Union Pacific No. 119 at the joining of the rails of the first transcontinental railroad at Promontory Summit, Utah, on May 10, 1869. And BTW, the 35 was backdated to represent B&MR for the 50th anniversary celebration of the Burlington's arrival at Denver in May 1882. It carried B&MR lettering for that, but by the next year when it went to Chicago's Century of Progress Exhibition it had been relettered CB&Q.

The 307 was built at Aurora in 1878 (along with engines 308-310). It was renumbered 1307 in 1898 and KCStJ&CB 555 in 1900. It was sold on May 30, 1903, to an unknown buyer. Had it survived a year longer it would have become a member of the A-2 class.

Number 440 was built by Hinckley Locomotive Works in December 1883 ( c/n 1657 ) as CB&Q 445, becoming Burlington & Missouri River Railroad number 156 in 1886. In 1904 it was renumbered to CB&Q Class A-2 324. In July 1916 it was rebuilt at Havelock and renumbered 440. In July 1926, it was sold for $3,000.00 to Pete Hedgpeth as Rock Port Langdon & Northern 440 and fitted with a slopeback tender from a Kansas City Terminal switcher. In 1940, the Burlington celebrated their 90th Anniversary. As it happened, Number 35 ( Burlington's exhibition 4-4-0 ) was at the New York World's Fair, which the Q did not wish to disturb. So the 440 was borrowed from the RPL&N, fitted with a diamond stack and long cow catcher at the Saint Joseph, Missouri shops, and a rectangular tender from a retired A-2 ( the original had rusted out ), and sent on tour of Lines East locations as B&MR 156 ( notably, Lincoln and Council Bluffs ), but for the appearance at Aurora it was repainted to CB&Q 440. When it exhibition duties were finished, the 440 was returned to the RPL&N and reunited with the slopeback tender. The 440 made its last trip on the RPL&N on November 11, 1945 after that road suffered two track washouts. The assets of the RPL&N were sold off, and the 440 was scrapped in the summer of 1953.
