The Old Head Freight Train is a corded desktop ball vape that extracts a full 0.4 g bowl in 1-2 draws through approximately 60 ruby spheres housed in Grade 2 titanium. It uses PID-controlled convection heating and connects to a water pipe with a 14 mm female joint through the included glass extraction chamber. It also ships with two features uncommon in the category: an integrated safety stand and a pre-installed coil guard.
Old Head has been designing ball vapes for years. The Freight Train replaces the Hot Rod and three previous iterations, consolidating years of refinement into one complete kit. Priced mid-range among ball vapes, it undercuts flagship options while bundling safety features that budget alternatives leave out entirely.
We tested the Freight Train through dozens of bowls and found it delivers the raw extraction power the category is known for. It comes in a tidy kit with the stand and coil guard built in. It earns a place on our best ball vaporizers list and ranks among our best desktop vaporizers, with a few trade-offs worth understanding before you buy.
We scored it 8.5 overall, with 9.2 for build quality and 9.0 for vapor quality. Portability (7.5) is its lowest score: it's corded, it needs a water pipe, and every cold start begins with a 120-second heat soak.
Heads up on stock: when we checked in September 2026, Old Head's store showed its products out of stock while the company moves warehouses. Check retailer stock, and make sure you're getting the right mains version for your country. Old Head's store lists the current kit as the Freight Train Pro Kit with the Pro Engine, so check that the listing matches the version you want.
Complete Kit Ships Ready to Vape
The Freight Train arrives assembled with everything you need except glass. Inside the box:
- Grade 2 titanium injector head pre-loaded with approximately 60 ruby spheres (4 mm each)
- PID temperature controller with integrated metal stand
- Heating coil (pre-installed)
- Coil guard (pre-installed)
- Glass extraction bowl with wire screen
- Handle
- Power cord (110 V North American)
- Extra screens
- Instruction booklet
No water pipe is included. You'll need a piece with a 14 mm female joint (the included extraction chamber outputs 14 mm male). An 18 mm extraction chamber is available separately for larger rigs. Our ball vape setup guide covers glass selection, heat soak timing, and first-session technique.
You need to source very little yourself: the glass adapter, power cord, PID controller, braided coil cable and titanium injector head are all in the kit.

Grade 2 Titanium Body With Pre-Installed Coil Guard
The injector head is machined from Grade 2 titanium. At 300 g for the head alone, it feels solid and planted in the hand. The titanium surface shows zero machining flaws, and the fit between components is tight throughout.
Inside, approximately 60 ruby spheres (4 mm each) create the thermal mass that converts coil heat into pure convection airflow. The heater itself is screenless, and air touches only titanium and ruby on its way through. From there it passes through the glass bowl and into your water pipe.
The 2024 redesign attached the ball vape rest directly to the PID controller base, so the hot head always has a dedicated spot right next to the controller. That's a clear step up from hunting for a safe place to set it down. Route the coil and power cables so nobody snags them.
The pre-installed coil guard is a physical shield around the heating element. Ball vape coils run hot enough to cause instant skin burns on contact. The guard doesn't make the head safe to grab while it's powered on, and the coil still gets extremely hot, so keep your hands clear of the head and shield. What it does is put a barrier between your fingers and the coil while you load or reposition.
The connections behind the controller are just as tidy as the head itself. The back panel layout is simple: an XLR jack for the coil and a standard power inlet, with nothing else to fuss over.

Ruby Spheres Convert Coil Heat Into Convection
The Freight Train's PID controller heats the coil to the number you set. That number is the heater's temperature, not your cannabis's, so don't copy over the setting you use on a portable. The approximately 60 ruby balls absorb that heat and distribute it evenly. When you draw through a water pipe, air passes over the heated rubies and through the cannabis in the bowl, extracting terpenes and cannabinoids through convection. Your cannabis sits in its own glass bowl below the heater.
Heat soak takes approximately 120 seconds from a cold start. Set your temperature, wait for the rubies to reach equilibrium, then load and draw. Rushing the soak produces thin, underwhelming hits, so patience here pays off.
With the controller at 230-260°C, the Freight Train fills a water pipe chamber with thick, visible vapor on a single draw. Draw resistance is almost nonexistent. This is one of the airiest ball vapes we've tested, and that openness produces enormous hits if you draw aggressively. New users should start with short, cautious pulls while they learn how much vapor the wide-open airflow actually delivers.
Above 280°C on the controller, extraction turns aggressive. A 0.4 g load finishes in 1-2 draws, leaving behind evenly browned AVB. In our testing, the Freight Train extracted thoroughly enough that a single bowl delivered strong effects even from moderate-quality cannabis.
| Controller setting | What you get |
|---|---|
| 230-260°C | Thick vapor on a single draw |
| Above 280°C | Aggressive extraction, a 0.4 g bowl done in 1-2 draws |
The Freight Train operates as an on-demand vaporizer, pulling heated air through the bowl only while you draw, so you can pace each bowl however you like. The standard model is built for flower. The concentrate dish belonged to the older Fusion configuration and isn't part of this kit. For a full breakdown of how temperature affects flavor and effects, see our vaporizer temperature guide.
Old Head's Corded PID Controller Delivers Zero-Downtime Sessions
The Freight Train runs on wall power through its PID controller. Old Head lists the North American model at 110 V, 60 Hz, 1 A, so check the label if your outlets run something else. No batteries, no charging cycles, no capacity loss over time. Once the heat soak completes, the controller holds your set temperature for as long as it's on. Pack a fresh bowl and draw again whenever you're ready, then switch it off when the session is over.
Temperature stability matters because inconsistent heat causes uneven extraction. The Freight Train's PID holds its target reliably across consecutive bowls with no perceptible drift.
This is a desktop vaporizer with zero portability. It stays on your desk, plugged in, paired with a water pipe. That limitation comes with a benefit: unlimited session length and no battery anxiety, ever.
Load, Draw, Stir, Done in Under Two Minutes
Loading the Freight Train takes seconds. Grind your cannabis and fill the glass bowl (up to 0.4 g). Place the bowl on your water pipe's 14 mm joint (or 18 mm with the optional chamber), and lower the heated injector head on top. Draw through the water pipe. After 1-2 hits, stir the cannabis with a tool, take another draw, and the bowl is done.
The learning curve is moderate. Mechanically, the Freight Train is simpler than many ball vapes (no airflow adjustments, no multi-piece assembly), but managing draw speed, temperature selection, and stirring technique takes a few sessions to dial in. Start low with short draws and work your way up as you get comfortable.
Cleaning demands minimal effort. Switch the Freight Train off, unplug it and let it cool before you touch anything. Replace the bowl's wire screen when airflow drops (extras ship in the kit). For deeper cleaning, soak the glass in isopropyl alcohol, rinse it well and let it dry fully. Keep alcohol away from the controller and coil, and follow the included instructions for the heater.
Safety requires constant attention. The coil guard and integrated stand make handling easier, but the head and guard still get extremely hot during operation. Never leave the Freight Train powered on unattended. Always return the head to its stand between draws.
Freight Train vs FlowerPot, Universal Baller and MiniNail
The Freight Train sits in the mid-range of the ball vape market. Old Head also makes the wireless Terp Hammer, but the corded Freight Train delivers better extraction consistency and stronger value. Here's how it lines up against the ball vapes buyers most often weigh it against.
| Vaporizer | Our score | Heating | Heater balls | Power | US list price |
|---|---|---|---|---|---|
| Freight Train | 8.5 | Convection | About 60 rubies | Corded | $399 |
| Universal Baller | 8.4 | Hybrid | 500 to 1,000 rubies | Wired or wireless | $500 |
| FlowerPot B1 | 8.2 | Convection | About 100 rubies | Corded | $515 |
| MiniNail Flower Wand | 8.2 | Convection | Ruby or quartz pearls | Corded | $299 |
Freight Train vs FlowerPot B2
The FlowerPot B2 is discontinued but remains one of the highest-performing ball vapes in our testing. Both use ruby-ball convection through Grade 2 titanium, and in hand the two heads are closely matched in footprint. The B2 supported simultaneous cannabis-and-concentrate extraction through its seven-hole dish, something the standard Freight Train doesn't replicate, and required a longer 180-second heat soak.
If you're buying now, the FlowerPot B1 8.2 is Cannabis Hardware's flower-only option, with a 19-hole titanium top and a separate 22 mm diffuser that takes mesh or machined screens. It's the more relevant head-to-head for anyone choosing between a Freight Train and a current FlowerPot product.
Freight Train vs FlowerPot B-Zero
The FlowerPot B-Zero also runs ruby-ball convection on a 20 mm coil. You can buy the head on its own and add the coil and supporting parts, or get Cannabis Hardware's complete kit with a PID controller, coil, bowl and insulated heat post. That full kit is the fair comparison. The Freight Train's integrated stand and coil guard make it the better standalone first ball vape, while the B-Zero suits buyers already building around Cannabis Hardware gear.
Freight Train vs Universal Baller
The Universal Baller 8.4 comes in metal and quartz-lined configurations, with both wired and wireless operation. The metal build packs 1,000 rubies and the wireless quartz setup uses 500, either way far more than the Freight Train's roughly 60. It also costs more, by an amount that depends on the configuration you pick.
In its quartz-lined setup, we preferred its flavor at lower settings, and it extracted harder per draw. If your budget reaches flagship pricing, the Universal Baller is the stronger vape. The Freight Train holds its own by delivering serious extraction at a lower price with a simpler corded setup. See the full side-by-side comparison.

Freight Train vs MiniNail Flower Wand
The MiniNail Flower Wand 8.2 is our budget pick. It scores 8.2 overall against the Freight Train's 8.5, but edges it on vapor quality (9.3 vs 9.0) and costs $100 less at US list price. It's also a corded PID ball vape that runs through your own water pipe, and it takes a bigger 0.5 g bowl. The trade-off is handling: the Flower Wand's heated wand is exposed and parks on a light metal stand, while the Freight Train builds its stand into the controller and adds a coil guard. Pick the Flower Wand to save money, and the Freight Train for easier handling.
Who Should Buy the Freight Train
Former smokers who still want a big hit. Through a water pipe, the Freight Train pulls thick, heavy clouds of vapor instead of smoke. That makes it a satisfying choice for anyone switching from smoking to vapor.
Safety-conscious first-time ball vape buyers. The integrated stand and coil guard make a hot ball vape less nerve-wracking to handle, though the hot head and guard still demand care.
Desktop users who want everything in one box. No sourcing a separate stand, no hunting for a coil guard, no assembling parts from multiple vendors. It arrives complete and ready.
Skip it if:
- You want to vape away from your desk. It's corded and needs a water pipe.
- You hate waiting. Every cold start means a 120-second heat soak.
- You want to vape concentrates. The standard kit is flower only.
Final Verdict
The Old Head Freight Train delivers serious ball vape extraction with a stand and coil guard built in. Its Grade 2 titanium and ruby heater, paired with a glass extraction bowl, produces dense vapor that clears a 0.4 g bowl in 1-2 draws.
It won't match flagship ball vapes in thermal mass or vapor path purity, and every cold start begins with a 120-second wait. At its price point, we consider the Freight Train a solid recommendation for buyers who want raw convection power with genuine safety guardrails built in.
