Most stations will have a wide range preflop, as their main game is seeing flops and playing from there. It is tough to put them on a range, but if we 3bet preflop, we can(sometimes) get rid of their weaker holdings such as T7s, 75s, hands like that. Also, you always want to give stations very bad odds to call preflop. So, if you usually 3bet something around 3-4x the initial raise, try going bigger with your stronger hands, giving them a bad price to see a flop. This will fold their weakest hands, and give you more money when they flop a pair to your overpair.
Another thing like has been stated above- do NOT try to bluff a station. Maybe after playing with certain players and learning their tendencies you can attempt a bluff, but there really is no reason to otherwise. If they flop a pair or a draw, they likely aren't going anywhere and even on brick turns and rivers, if they have a piece, their plan is to call you down.
