In the 1910 recoding, Second Class fixed wheel cars coded _B__ were relettered to Y. The numbers were altered as well to remove gaps when cars in the 'B' group had been scrapped and not replaced.
The numbers run 1 - 385. This number group is also shared by _YH_ cars. The Y numbers recorded by the author are:
4, 5, 7, 17, 20, 22, 30, 31, 33
38, 52, 54, 63, 65 - 69, 77, 89, 91
93 - 96, 98, 100, 102 - 208, 212, 213,
217 - 224, 230 - 247, 250, 251, 253, 257, 258
267, 270 - 272, 276 - 279, 288, 289, 292, 294
299, 300, 302, 303, 306, 309, 315, 320 - 322
325, 326, 329, 330, 333, 336, 337, 339,
342 - 344, 347, 348, 350, 351, 357, 358, 360
361, 363, 366, 369, 371 - 378, 383, 385
Two hundred and sixteen cars were relettered in the 1910 recoding with four cars converted into the class between 1913 and 1922.
The cars were progressively removed from service between 1911 and 1935 by scrapping or conversions to _W__ works sleepers.
The remaining few cars, sited at loco depots, were removed and scrapped by 1956.
One car survived to 1963 as a railmotor trailer on a distant branch line. The car Y 309, was restored and is now part of the 'Veteran train'.
