Rutherford County
An assembly plant, its own rail yard, and a quarry
Three things are filed under Smyrna and no two of them are the same trade. Nissan runs a vehicle assembly plant. CSX Transportation holds a rail yard recorded as Smyrna Nissan Plant, 2.74 miles from the middle of town and the only rail row here. And SRM Materials works a crushed-stone quarry with ten people, approved for state highway work and matched to the register at 0.04 miles.
The rail yard is one of thirty-eight rows in this dataset named for a vehicle manufacturer, and one of twelve naming an assembly plant specifically. Tennessee holds three of those twelve — this one, the Volkswagen yard at Chattanooga, and Spring Hill Plant.
What actually moves through it could not be established from anything we read, so this page says the yard is here and stops.
The town name is a district, not a business
That quarry comes with a trap in the paperwork. Two separate rows carry the Smyrna name in Rutherford County, and the state register holds them under two different approved producers — Martin Marietta at one and SRM Materials at the other.
So “the Smyrna quarry” identifies a district rather than an operation. A truck described that way could have come off either fleet, and the two run to different specifications and different replacement cycles.
If you are selling one, the operator is the thing to say. It is what separates two machines that otherwise look identical on paper, and it is the question a buyer will ask second after the hours.
The road network
A county that keeps building the bridges it needs
Both of those fleets run over a network that restricts very little of itself. Rutherford County maintains 168 bridges and posts 14 of them, 8.3 per cent, which is low for a stock that size.
The reason is growth. Rutherford has been among the fastest-growing counties in the United States, and a county that is growing builds structures rather than nursing them. New bridges do not get posted, so the rate stays down while the network gets bigger.
Within ten miles of the SRM Materials pit there are 223 structures and only 13 posted, 7 of them county-maintained, the nearest 2.5 miles out. The lowest raw rating is 3.9 tonnes, below an empty tandem dump and not a crossing this trade uses; the cap that binds a loaded truck is 14.9 tonnes.
FHWA National Bridge Inventory 2025, Tennessee file, items 21, 41, 64 and 70. Tennessee codes item 41 more broadly than neighbouring states, so the true count of load restrictions is lower than the posted count suggests.
Tennessee weight law
The plainest position of any fleet in the state
The plant fleets get the sharpest version of the state’s weight rules, and it is one to state plainly because it is unusually clean.
Tenn. Code Ann. § 55-7-203 sets 80,000 lb gross, 20,000 lb on a single axle and 34,000 lb on a tandem, with up to 550 lb more for emissions-reduction equipment. Subsection (b)(7) grants a ten per cent margin of error on the weighing to eleven named classes — logging, sand, coal, clay, shale, phosphate, solid waste, recovered materials, farm trucks and machinery trucks — and only off the interstate system.
All three Tennessee assembly plants sit on the interstate network, where that margin does not apply, and automotive parts are not among the eleven classes in any case. Both doors shut. For those trucks it is 80,000 lb with no allowance of any kind on every road they use.
The quarry side is no better off: crushed stone is on none of those lists either, and Tenn. Code § 47-26-812’s axle shield and five hundred pounds are off-interstate only.

Tennessee paperwork
We need a title — unless it never had one
Beyond the weight rules, that is the whole of it.
Everything after that sentence is a fix rather than a category. A lost title has a counter replacement. Where none exists there is a bonded route. Neither one stops a sale.
The salvage rule is the one to get right, because the short version is wrong. Tennessee’s salvage and rebuilt part is built on the term passenger motor vehicle, and § 55-3-201 defines that as a vehicle ten model years old or less which, if it is a light-duty truck or a multipurpose vehicle, is rated at not more than nine thousand pounds gross.
So the seventy-five per cent threshold does not reach a truck rated above nine thousand pounds at any age, and does not reach a vehicle of any kind over ten model years old. Those limbs describe the class the part governs rather than exceptions inside it. Whether some other provision reaches such a vehicle was not determined and is not asserted here.

What we buy here
All of that iron is iron we buy. Day cabs and road tractors off the plant runs and the rail yard 2.74 miles out. Car haulers, because an assembly plant is where they work. Tandem dumps and aggregate haulers off both Rutherford County pits, the Martin Marietta one as well as ours.
Box trucks, straight trucks, flatbeds, rollbacks, sleepers, tankers, service bodies, work trucks and pickups too — not a Rutherford County thing in particular, they run everywhere.
Whatever you drive, the offer doesn’t change. We buy all of them.
We buy complete trucks. If the engine, transmission, doors, rear ends, drive shafts, wheels or anything under the hood have been removed, we can’t buy it. Small things — a missing bumper — are fine.
Straight answers
The questions we get asked in Smyrna
- Does it have to run?No. It does have to be complete — if the engine, transmission, doors, rear ends, drive shafts, wheels or anything under the hood have been removed, we can’t buy it. Rust is not a disqualifier.
- The engine is out of it. Is that different?Yes, and that is the line. A tired engine is fine; an engine that has been pulled and sold means we can’t buy the truck.
- What about the title?We need one unless the truck is old enough that it never had one. Lost titles have a counter replacement, and where none exists there is a bonded route.
- Do you buy car haulers?Yes, and around Rutherford County there are more of them than most places. Tell us the deck configuration and whether the hydraulics still work.
- Which Smyrna quarry did it run for?Say if you know. Martin Marietta and SRM Materials both have a pit filed under this town, and the operator is what separates two otherwise identical machines.
- How do you pay?Cash or electronic payment, whichever suits you.
Why people call
Beyond a tractor that has simply done its runs, the reasons here are personal ones. Retiring. A DOT physical that did not go the way it used to. A plant contract that ended and left a unit standing with nothing booked.
The yards across Rutherford County and out towards the Martin Marietta pit usually have one that has not moved since the last run finished.
Most of those aren’t happy reasons, and we don’t treat them like they are. Somebody wants a straight answer and the truck gone by the end of the week. That’s what we’re here for.
