The agency currently operates 9 Connector bus routes, mostly in the city of Frederick, 5 shuttles, and demand-response for seniors and persons with disabilities.

In April 2014, the fare for a one-way trip using Transit for the general public was $1.25 with a monthly pass costing $45.00.

Ten trip passes can be purchased for $12.00 for the general population, $8.00 for students and youth, and $5.50 for seniors and disabled persons.

If the bus needs to deviate from its normal route for a stop, an additional $1.50 is charged to the passenger and 24 hours heads up must be given.

Currently, the fleet subsets are replaced and returned on average every 14 years, the maximum service life for a bus permitted by Maryland law.

A temporary bus, #959, a Champion Defender, thirty-foot bus was acquired used to make up a shortfall in the roster until new buses on order arrive in mid-2021 to begin replacing the 2010 Gillig Advances buses which are now at the end of their usable service life.

[4] In June of 2023, TransIT Gillig Advantage bus 981 had been retired with 982-986 expected to follow suit due to state service life requirements.

In February 2025, D40LFRs 40227 which had not been placed in revenue service due to ongoing mechanical issues was removed from the active fleet roster.

Frederick City's first new bus order consisted of 1981 vintage TMC T-30 Citycruiser thirty foot buses (a license-built version of the Ontario Bus Industries (OBI) Orion I), which served the original Red and Blue Routes and were numbered 200–203.

Due to acceptance testing delays, TransIT operated for several weeks under a combination of the original TMC/Orion I fleet and three thirty foot Flxible Metro buses on loan from Maryland MTA.

Rather than delay service for 13 months, five small front engine used Spartan/Champion "Breadboxes" (re-badged, Goshen "Transette" buses) were purchased for short term use.

In 2015, TransIT placed an order for five re-manufactured, Gillig Advantage all-electric buses from Complete Coach Works (CCW).

All of the breadboxes arrived with front entry doors and a rear wheelchair lift at the very back end of the coach.

TransIT routes are ten based, with the first digit designated to the part of the city/county the bus runs outbound to.

80 line routes serve the north end to the northwest side of the city including Ft. Detrick and the Yellow Springs area.
