Following the cessation of all rail services, the company provided only road transport. It purchased second-hand vehicles from a number of operators, including Ulsterbus, and obtained vehicles on loan from CIÉ. The company operated passenger bus services, freight services, and holiday tour services, as well as providing school bus services for many schoolchildren in Donegal. However, it failed to be profitable throughout the 1970s, and was purchased from bankruptcy by Patrick Doherty, a Buncrana businessman, in 1981. The company maintained offices at the Foyle Street Bus Depot in Derry, and in Letterkenny Bus Depot in Donegal. It also had large garage areas in Derry and Letterkenny, where it kept its fleet of buses. The majority of its bus fleet, with the exception of those used for holiday touring, was more than 10 years old, mainly considering of 1994 registered Dennis Dart vehicles.
