The R29 was a New York City Subway car model built by the St. Louis Car Company in 1962 for the Interborough Rapid Transit Company, IRT A Division (New York City Subway), A Division. A total of 236 cars were built, arranged in married pairs. The R29s entered service on April 28, 1962, and received air conditioning by 1982. The fleet was rebuilt by Morrison–Knudsen between 1985 and 1987. The R29s were replaced in 2001 & 2002 with the delivery of the R142 (New York City Subway car), R142 and R142A (New York City Subway car), R142A cars, with the last train running on October 24, 2002. After being retired, most R29s were sunk into the ocean as artificial reefs, but two cars have survived. Description The R29s were numbered 8570–8805. Between 1985 and 1987, the R29s were overhauled under contract ''R99''. Therefore, the cars are also known as R99s in their post-overhaul state.

R99 has a peculiar spectrum that has been described as OBf:pe, "unclassifiable", peculiar WN10, "similar to the unusual LBV HD 5980 HD 5980 is a multiple star system on the outskirts of NGC 346 in the Small Magellanic Cloud (SMC) and is one of the brightest stars in the SMC. HD 5980 has at least three components among the most luminous stars known: the unusual ...", "unique", and Ofpe/WN9. The Ofpe/WN9 type remains even though other stars of this type have been reclassified to types between WN9 and WN11. R99 has significant differences from those other stars which preclude it being given a simple WN spectral type: the ultraviolet spectrum is strongly blanketed over a different range of wavelengths; highly ionised iron lines are seen in absorption instead of emission; th ...
