VapeExperts Review of the Freight Train
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, connects to any 14 mm water pipe via the included glass extraction chamber, and ships with two features uncommon in the category: an integrated safety stand and a pre-installed coil guard.
Old Head's founder Brian has been designing ball vapes since before the category had a name. 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, wrapped in a more complete and safer package than most alternatives. It earns a place on our best ball vaporizers list, with a few trade-offs worth understanding before you buy.

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.
Grade 2 Titanium Body With Pre-Installed Coil Guard
The injector head is machined from Grade 2 titanium, the same alloy found in surgical implants. 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 vapor path contacts only titanium and ruby throughout. No plastics, adhesives, or solder sit anywhere in the airstream.

Every vaporizer we cover is bought, lived with, and tested by the same small team. We log temperatures with an external thermocouple, run battery cycles to depletion, and spend at least two weeks on a device before we score it. No manufacturer has ever paid for, previewed, or influenced a review on this site.
The 2024 redesign attached the ball vape rest directly to the PID controller base. Both ends of the power cord anchor to the same unit, so the entire setup resists tipping. Previous Freight Train versions and most competitors use separate freestanding stands that topple if the cord gets snagged. This integrated approach is a clear step up.
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 powered on, but it blocks the most common accident: brushing an exposed coil while loading or repositioning.
60 Ruby Spheres Convert Coil Heat Into Pure Convection
The Freight Train's PID controller heats a coil to your target temperature (200°C to 315°C in 1°C steps). The approximately 60 ruby balls absorb that heat and distribute it evenly. When you draw through a water pipe, ambient air passes over the heated rubies and through the cannabis in the bowl, extracting terpenes and cannabinoids without combustion. This is pure convection with no direct contact between a heated surface and your herb.
Heat soak takes approximately 120 seconds. 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.
At moderate temperatures (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, extraction turns aggressive. A 0.4 g load finishes in 1-2 draws, leaving behind evenly browned AVB. Community users consistently describe the potency catching them off guard on their first session, and our testing confirmed: the Freight Train extracts thoroughly enough that a single bowl delivers strong effects even from moderate-quality cannabis.
The Freight Train operates as an on-demand vaporizer, extracting only while you draw with no vapor wasted between hits. It also supports concentrate use, though its design is optimized for dry herb performance. For a full breakdown of how temperature affects flavor and effects, see our vaporizer temperature guide.
The Freight Train runs on wall power through its PID controller with 1°C precision from 200°C to 315°C. No batteries, no charging cycles, no capacity loss over time. Once the 120-second heat soak completes, the vape holds your set temperature indefinitely. Pack a fresh bowl and draw again whenever you're ready.
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, 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. Starting around 200-230°C helps beginners build comfort before moving to higher temperatures.
Cleaning demands minimal effort. Set the PID to maximum and let the unit burn off residue for 5 minutes. Replace the bowl's wire screen when airflow drops (extras ship in the kit). For deeper cleaning, soak glass components in isopropyl alcohol. The ruby balls and titanium head stay clean through regular burn-offs.
Safety requires constant attention. The coil guard and integrated stand reduce the two biggest ball vape risks, but the heating element remains exposed and the injector head gets extremely hot during operation. Never leave the Freight Train powered on unattended. Always return the head to its stand between draws.
How It Compares
The Freight Train occupies the mid-range of a growing ball vape market as of May 2026. Old Head also makes the wireless Terp Hammer, but the corded Freight Train delivers better extraction consistency and stronger value. Here are the three most common cross-shop decisions.
Freight Train vs FlowerPot B2
The FlowerPot B29.3 is discontinued but remains one of the highest-performing ball vapes in our testing. Both use ruby-ball convection through Grade 2 titanium. The B2 supported simultaneous herb-and-concentrate extraction through its seven-hole dish, something the standard Freight Train doesn't replicate, and required a longer 180-second heat soak.
For buyers shopping in 2026, the FlowerPot B19.0 is Cannabis Hardware's current flower-only option with freer airflow and a mesh-top design. 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-Zero7.9 uses the same 20 mm coil platform and ruby convection but ships as a bare head with no coil guard, no handle, and no stand at a lower price. The Freight Train's complete kit is the better standalone first ball vape, while the B-Zero wins on ecosystem flexibility: its coil and PID can drive higher-tier Cannabis Hardware heads later.
Freight Train vs Universal Baller
The Universal Baller9.2 packs 1,000 ruby balls versus the Freight Train's 60, routes vapor through an all-quartz-and-glass airpath with no metal contact, and offers both wired and wireless operation. It costs roughly 25% more.
That glass-only vapor path produces cleaner flavor at lower temperatures, and the massive thermal mass extracts 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 cost with safety features the Universal Baller doesn't include. See the full side-by-side comparison.
Who Should Buy the Freight Train
Former combustion users who want equivalent hit intensity. The Freight Train matches the physical impact of a bong rip while eliminating smoke, making it one of the strongest paths for anyone switching from smoking to vapor.
Safety-conscious first-time ball vape buyers. The integrated stand and coil guard address the two most common ball vape accidents. No other ball vape at this price ships with both features.
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.
Final Verdict
The Old Head Freight Train delivers serious ball vape extraction in the safest mid-range package available as of May 2026. Grade 2 titanium, a ruby-only vapor path, and wide-open airflow produce dense vapor that clears a 0.4 g bowl in two draws.
It won't match flagship ball vapes in thermal mass or vapor path purity, and every session starts with a 120-second wait. At its price point, VapeExperts considers the Freight Train a solid recommendation for buyers who want raw convection power with genuine safety guardrails built in.
