FIELD: railway transport; tie-preparation plants.

SUBSTANCE: invention can be used for treatment of ties at tie impregnation plants. Proposed flowline contains tie-pricking including tie feeder, sawing unit and pricking machine with cross accumulation conveyor to remove ties from pricking machine, section for preventing cracking of ties including parallel longitudinal conveyors with reversible machine tools for drilling holes in ties, thread cutting and driving in screws placed between conveyors. Parallel longitudinal conveyors are arranged square to cross conveyors of tie-pricking section. Additional longitudinal conveyor is placed between parallel longitudinal conveyors being mechanically coupled with accumulation conveyor provided with tie cutoff arrangement for delivering ties one by one to additional conveyor. Additional and parallel longitudinal conveyors are furnished with device for in-turn delivery of ties from additional longitudinal conveyor to parallel longitudinal conveyors made in form of two reciprocating U-shaped receiving pockets arranged over support surface whose dimensions correspond to dimensions of tie, and distance between axes of receiving pockets corresponds to distance between axes of additional and parallel longitudinal conveyors. Cutoff arrangement includes support platform adjoining support surface of additional conveyor equipped with side limiter in slots of which rollers of two levers for engagement with side surface of tie are hinge mounted. Each lever is furnished in its middle part with power cylinder provided with support on its rod to press tie to platform.
