Pull up any loose or wobbly timbers that aren't anchored down by hand. Have a friend help you lift the railroad timbers, as they can be exceptionally heavy. Form a pile of the timbers in one place, either close to your garbage pickup location or where you can easily reach the pile with a truck.
Wedge a shovel head under any timbers that don't shift when you push on them. Push down on the shovel handle to use it as a lever and raise the timber from the ground. Reposition the shovel as needed and push down again until the timber is loose. Place the timbers in your pile.
Use a crowbar or pry bar on timbers that are nailed to the ground to remove the long nails and free the timber. For large spikes or rebars, you may have to dig down into the ground to free the timber. Lift the timbers once they are no longer anchored to the ground and place them in the pile.
Continue lifting and removing the railroad timbers from their current location until you have collected all of them. Gather any pieces or chunks from the ground that have broken off from the ties. Discard smaller hand-sized pieces in a trash bag and place larger pieces in your pile.
Contact your city or county waste facility to arrange for bulk pickup collection or find out the appropriate location for drop-off in your city. If you live in a rural area where you typically take your trash to a dumpster, contact your town's local waste management authority to determine if taking your timbers to the dumpster is appropriate or if you need to arrange for a manual pickup.
