Built for Rail Car Manufacturing.
Hopper bodies, tank shells, gondola sides, draft sills, structural gussets. Piranha equipment runs on the line at North America's rail car OEMs — with Bertsch plate rolls that trace their heritage to 1879, exactly when this industry was born.
Why Piranha
Why Rail Car OEMs Choose Piranha
Three reasons rail car manufacturers and conversion shops run Piranha on their lines.
Bertsch Heritage Since 1879
145+ years of plate-rolling history — the same era this industry was born. Bertsch plate rolls form hopper bodies, tank car shells, gondola sides, and dipper bucket curves at the scale and accuracy rail car production demands.
Service That Shows Up
When a press brake stops mid-run, you don't have time for a ticket queue. Piranha service is U.S.-based — phone support that answers, in-stock parts shipped same-day from Belvidere, IL, and PM programs scaled to your shift schedule.
One Source for the Whole Line
Bertsch plate roll, Flex Series LASER, Whitney Combo, press brake, shear, ironworker — every machine from one manufacturer, with one quote, one install team, and one parts catalog.

How Piranha Speeds Up Your Line
Four ways Piranha equipment changes the math on rail car manufacturing.
Frequently Asked Questions
Common questions from rail car OEMs, conversion shops, and procurement teams.
What plate diameter and thickness can the Bertsch rolls handle for hopper bodies and tank shells?
Bertsch plate rolls are configured for the customer's application — diameter and thickness specs vary by model. For hopper bodies and tank car shells, the heavy-spec Bertsch configurations are industry-proven across Trinity, Greenbrier, FreightCar America, and other major rail car OEMs. A specialist will scope the right configuration for your part mix.
When does LASER cutting make more sense than plasma for rail car structural prep?
LASER wins for thinner plate (under 1″) where edge quality matters for downstream welding — side wall panels, roof plates, slope sheets. HD plasma on the Whitney Combo handles thicker plate (1″ to 3″) at faster speeds and lower per-part cost — bolster plates, draft sills, underframe structural. Many production lines run both side-by-side.
Can the Flex Series handle full-thickness side sill plate in one pass?
Depends on power level. The 12kW and 20kW Flex Series configurations handle the thick plate work that defines rail car structural — side sills, draft sills, center sills. A specialist will scope the right power level for your specific part thickness mix.
Conversion / rebuild market — does Piranha equipment fit a mixed production + conversion shop?
Yes — this is exactly the kind of mixed-work shop Piranha is built around. Quick tool change on the ironworker, fast offline programming on the LASER, and flexible automation mean the same line runs new-build production one week and a conversion / rebuild order the next.
What's the install timeline for a complete rail car fab line?
From signed order to first part: typically 16–24 weeks depending on automation scope, machine count, facility readiness, and electrical/utility prep. Piranha application engineering coordinates with the customer's plant team through every stage.
What training and support comes with the equipment?
Every machine ships with installation support, a video tutorial library, comprehensive operations manuals, remote desktop support, and lifetime phone support from the U.S.-based technical team. On-site application engineering coordinates with your plant team through install.
Do you offer financing for capital equipment?
Yes. Piranha offers flexible financing options for capital equipment purchases — useful for managing rail car line investments across multiple machine orders or staged automation rollouts.
Does Piranha support multi-shift production lines?
Yes. LASER automation handles material loading and unloading across shifts, PM programs are scaled to your shift schedule, and parts inventory is sized for high-utilization production environments.
