Class Talisman (Locobase 2553)

Profiled in White (1968), this engine is not attributed to any particular railroad (although the Erie was a 6-foot gauge railroad). Later research in rosters prepared by Gene Connelly, GM Best and Robert Dubits, Jr; and Al Weber (all supplied to Locobase by Allen Stanley in August 2013) reveal that this was NJLW works number 185 from April 1857.

It is typical of the period, although it has a variation of the Stephenson link valve motion invented by H. Uhry & HA Luttgens. Although claimed to reduce fuel consumption by making fuller use of the steam, no real difference was noted. Moreover, the gear was expensive and the valve speed governor, a cam, tended to slip. Otherwise, the locomotive was typical of Paterson, New Jersey practice. (Paterson was then a major locomotive manufacturing center.)

The S&W succeeded to the Saratoga & Fort Edward in 1855. Its main line linked Saratoga Springs, NY--already a fashionable country getaway--to Castleton, Vt about 52 1/2 miles (84.5 km) away (the five miles from Fair Haven to Whitehall was leased from the Rutland & Whitehall). In 1866, the S&W was combined with the Troy, Salem and Rutland and the Rensselaer & Saratoga. Ultimately, these lines would all be owned and operated by the Delaware & Hudson.

NB: The direct heating surface (including the firebox heating surface) is an estimate calculated by subtracting the calculated tube heating surface from the reported total evaporative heating surface.
