I have found a DMR TIII system being used by FCPS, seems to just be the school busses. The callsign is WRJI389:

network ID, site, LSN, freq
2, 1.2, 691, 855.3125
2, 1.2, 1019, 857.3625
2, 1.2, 1091, 857.8125 [CC]
2, 1.2, 1343, 859.3875
2, 1.2, 1603, 861.0125
2, 1.2, 1607, 861.0375
2, 1.2, 1735, 861.8375
2, 1.2, 1747, 861.9125

Not 100% sure about the talk groups, I don't know how the areas work with the school busses. But I seemed to have worked these out
Talkgroup, Alpha Tag, Description, Function tag
11, Bus Disp1, School Bus Area 1 Dispatch, Schools
18, Bus Disp2, School Bus Area 2 Dispatch, Schools
21, Bus Disp3, School Bus Area 3 Dispatch, Schools
24, Bus Disp4, School Bus Area 4 Dispatch, Schools

I submitted to the database, just figured I'd post here in case anyone was interested or had any info about it. There's a huge amount of private calls on the system. Mostly just drivers chatting it seemed like.

1) any idea what they use their VHF trunked system (WRFJ472) for?

2) is WRJI389 just school buses or is it other FCPS related comms too? I think the obsolete P16 system had school buses and other countywide school-related comms too.

I'm hearing these frequencies all using Color Code 11, they're listed in the db as Color Code 0.
