Carries Life
Erciyas Rail builds five four-axle bogie tank wagons for liquid and gaseous cargo, from the 62 m³ Zaes for crude oil to the 117 m³ Zags for LPG. All are built for 1,435 mm standard gauge; RID compliance for dangerous goods is listed for the Zans 98, Zags 117, Zacens 78 and Zaes 62.
The Zags 117 has a spiral-welded tank, a method Erciyas Rail introduced to tank wagons in 2022 with its sister company Erciyas Steel Pipe. The spiral seam leaves no cross seams along the tank and reduces the number of T-joints to inspect by about 71%.
Weight and volume-optimised 98 m³ mineral oil tank wagon.
Designed for optimised LPG transport across European rail networks.
For high-temperature transport of heavy petroleum, bitumen and coal tar.
Optimised for transporting light petroleum products.
For transporting crude oil and heavy petroleum products.
| Model | Use | Capacity | Max. payload | Tare | Length over buffers | Tank code | Bogie |
|---|---|---|---|---|---|---|---|
| Zans 98 m³ | Tank · Liquid | 98 m³ | 67.5 t | Approx. 22.5 t | 16,400 mm | L4BH | Y25Ls-K (H-type) |
| Zags 117 m³ Spiral | Tank · LPG | 117 m³ | 57.5 t | 32.5 t | 18,000 mm | P27BH | Y25Ls-K |
| Zacens 78 m³ | Tank · Bitumen | 78 m³ | 65 t | Approx. 25 t | 16,240 mm | L4BH | Y25 Lsdi(f)-K |
| Zas 70 m³ | Tank · Light | 70 m³ | 65 t | Approx. 25 t | 14,540 mm | Liquid petroleum | Y25 Ls(s)d1 |
| Zaes 62 m³ | Tank · Crude | Min. 62 m³ | gross 80 t | n/a | n/a | L4BH | Y25Ls(s)1-K |
A conventional tank shell is made of rolled plate sections, each with a longitudinal seam, joined by circumferential seams; every crossing point is a T-joint. With spiral welding the shell is formed by one continuous helical seam. According to Erciyas Rail's engineering data this means about 71% fewer T-joints, 13% longer fatigue life under cyclic stress and 20 times faster tank production, with every seam inspected by ultrasound and X-ray.
Five models: Zans 98 m³ for mineral oil, Zags 117 m³ for LPG with a spiral-welded tank, Zacens 78 m³ for bitumen and heavy oil up to +190°C, Zas 70 m³ for light petroleum products such as diesel and gasoline, and Zaes 62 m³ for crude oil and heavy petroleum.
The Zags 117 m³. Its P460NL tank has the RID tank code P27BH, a maximum operating pressure of 27 bar and a working temperature range of -25°C to +40°C, on Y25Ls-K bogies.
The Zacens 78 has an external heating system rated 12 bar operating and 18 bar test pressure, with 100 mm rock wool insulation, for cargo up to +190°C. The Zaes 62 has a heating system for crude oil up to +165°C. Heating and insulation are optional on the Zas 70.
Deliveries include 340 tank wagons for VTG between 2024 and 2026 and 250 tank wagons for Iraqi Republic Railways between 2021 and 2022.
