7 Baynes-Richmond replaced the I.R.C.'s Hoyt Street car line.
The I.R.C.'s route 9 was Kenmore Avenue. Evidently it was discontinued and later restored as route 30.
Route 11 was originally Utica Crosstown. It followed Route 10 from the west side to Main Street, then Route 12 from Main Street to the east side. N.F.T. discontinued it. The modern route 12 follows the Utica Crosstown route.
The I.R.C.'s car route 17 was Elk Street. So far as I know, it was never a bus route.
19 Bailey-McKinley, now called just Bailey, is the second longest route within the city limits. Bailey Avenue is the longest street in Buffalo, and the route goes past its southern end, to McKinley Park.
The I.R.C.'s route 22 was called Connecticut. The Porter-Best bus, which corresponds to the I.R.C.'s car 25, goes through the same neighborhood but does not pass Connecticut Street.
23 Fillmore-Hertel is the longest route in the city. Fillmore Avenue is one of Buffalo's longest north-south arteries, and Hertel Avenue is one of Buffalo's longest east-west arteries. The bus goes the length of both streets and past the south end of Fillmore Avenue onto Smith Street.
27 Sheridan Parkside was consolidated into 25 Delaware as 25C during the route reorganization of the 1960s. Most of its route followed the Delaware Avenue route. The number 27 was later assigned to the Ridge Road route.
28 Sheridan-Englewood was discontinued in the 1960s. The number 28 was later assigned to a new route, Sheridan-Mill. It too was discontinued.
29 Niagara Falls, which ran on Niagara Falls Boulevard, was discontinued. A new route 34 now runs on Niagara Falls Boulevard, with a slightly different path.
31 South Buffalo Crosstown was also called Ogden-Tifft, because it ran on Ogden and Tifft Streets in South Buffalo. It no longer exists.

In the 1960s, NFT merged the BTC's routes with the numbered routes, creating new numbers for some of them: 33 was North Tonawanda, 34 was Elma, and 35 through 37 ran to Hamburg via Camp Road, South Park Avenue, and Abbott Road.
