Trackmania servers alone, can't store the players records, but they allow you to connect a program to control the entire server, so records can be stored, tracks can be jukeboxed, administration functions become available and much more.
And this is exactly what TRUCK does, you connect it to your Trackmania server and it start storing players records for each track, along with many others administrative functions.
The following screenshots are from the game with TRUCK connected to the game server.
