Under the leadership of Arrigoni, NYBS commenced Parkchester - Manhattan express bus service (now the BxM6) on August 24, 1970.

[9] Six more lines were added including a Co-Op City to Wall Street express bus service, later to be done away with.

The city made an initial buyout payment of two million dollars for rights to the Bronx express bus lines NYBS operated.

The MTA Bus Company (the successor to the private line operations) meanwhile agreed to pay Arrigoni and the other NYBS owners six million dollars annually for use of its depot and maintenance facilities for a period of twenty years, with an option to purchase afterwards.

[1][17] MCI D4500 2926 was donated to the Friends of the New Jersey Transportation Heritage Center in 2021, renumbered 1803 and was given a New York Bus Service livery.
