From 1 January 2027, the Ministry of Transport will impose a complete ban on the use of modernised tank cars that had previously been life-extended for chemical goods but were repurposed to transport petroleum products. This initiative aims to eliminate the 'grey' schemes for extending rolling stock service life that emerged during the wagon-building crisis of 2015–2016. We examine how this decision will affect the fleet balance and the fuel market.
The transport authority is preparing to fundamentally reshape the rules of the railway freight market by closing a regulatory loophole that allowed age‑written‑off tank cars to be operated for decades. According to a draft order dated 6 May 2026, from 1 January next year a complete ban will be introduced on including modernised tank cars that had previously been life‑extended for the transport of specialised chemical goods in train consists.
The roots of the current situation go back to 2015–2016, when Russian wagon‑building was in deep crisis and production of freight rolling stock fell by more than 54%.
At that time, to support the plants, the state imposed restrictions: it banned the extension of the service life of mass‑produced types of rolling stock, including hopper wagons and tank cars.
However, the market quickly adapted by finding an exception in the Technical Operation Rules (PТЭ). For wagons carrying highly specialised cargoes – from yellow phosphorus to pesticides – the possibility of modernisation and subsequent life extension of up to 16 years beyond the standard 32 years was retained.
In practice, this led to the emergence of 'grey' schemes. Rolling stock owners carried out modernisation of tank cars under a 'chemical' classification, which allowed them to legally operate the old fleet. The main tool was repairs at foreign facilities, for example at the Kazakhstani enterprise Ak‑Zhayyk‑7. The technological process made it possible to expand the list of permitted cargoes from a couple of dozen to three hundred items. This enabled owners to formally comply with the letter of the law while actually using the tank cars for mass transport of petrol and diesel fuel, thereby competing with owners of new rolling stock.
In the winter of 2026 the problem reached the ministerial level. At the time, the head of the Wagon Rolling Stock Directorate of Russian Railways' Central Infrastructure Directorate, Roman Khoykhin (subsequently detained by law enforcement, for more details read HERE), pointed out in a letter to Deputy Transport Minister Alexei Shilo the ambiguity of the Technical Operation Rules: the rules allowed the modernisation of a wagon type but did not limit the range of cargoes. At that time the Ministry of Transport did not see a violation, explaining that the rules applied to the wagon's design, not its contents. However, the authority has now decided to change its position, moving from controlling content to a complete ban on the very possibility of modernisation for all cargoes except heptyl and melange.
Today the situation looks like a battle for market integrity. Russian Railways (JSCo RZD) and the Union of Wagon Builders stress that the need for such 'exceptions' has passed. According to estimates from the Union, in 2026 industry is ready to produce 12–15 thousand new tank cars, which more than covers the decommissioning of 8,300 old units. Industry players believe the ban on 'chemical' life extensions will remove barriers to the introduction of innovative new models and ensure even utilisation of factories.
The question of how this will affect the fleet balance remains key. According to official data, just over 450 'life‑extended' tank cars are operated on the network. On the scale of the entire railway network this is a drop in the ocean, but the expert community is divided in its assessment of the consequences of such a step. To get the full picture, we turn to the opinions of key industry experts.
Since 2016, only wagons within their designated service life may be operated on the Russian Railways network. This means cargoes can be transported in wagons only as long as their age is less than that specified in the manufacturer's design documentation. This was implemented by including in the Technical Operation Rules a clause prohibiting the inclusion in train consists of wagons whose designated service life had been extended after 1 January 2016, says Alexander Polikarpov, Managing Partner and co‑founder of ROLLINGSTOCK Agency, speaking to VG.
'The general rule had a number of exceptions, in particular for wagons that were not being produced in Russia at that time, or wagons that were needed for state transport.
In the tank‑car segment, life extensions were conditionally permitted for models used for the transportation of yellow phosphorus, wine materials, heptyl, amyl, acetic acid, pesticides, alkylbenzene sulfonic acid, melange, milk, polyvinyl chloride, caprolactam, superphosphoric acid and sulfanol.
In 2025, the service life of a batch of petroleum‑petrol tank cars was extended by carrying out modernisation under the registered specialisation of 'pesticides'.
According to the documentation, these tank cars could also be used to transport a wide range of cargoes, including petroleum products. After the modernisation, the extended‑life wagons were used to transport petroleum products. This is how the ban on extending the life of petroleum‑petrol tank cars was circumvented.
Now, with the new changes to the Technical Operation Rules, the Ministry of Transport is closing the loophole. Under the new version of the Rules, the possibility of extension is retained only for tank cars transporting heptyl and melange. It should be noted that this change will not have a significant impact on the balance of the tank‑car fleet,' says the expert.
Other market participants also urge not to dramatise the situation, pointing out that petroleum product logistics are determined by other, far more significant factors.
'The need to renew the fleet of tank cars for transporting petroleum products will not greatly affect the fuel market, for which other factors are far more important: the amount of damping payments; the severity and duration of export bans; excise rates on light petroleum products; and finally, the volume of scheduled and unscheduled repairs.
This also includes railway tariffs for the transportation of petroleum products.
Against this backdrop, issues of tank‑car fleet renewal are a secondary factor, especially since, according to several experts, the tightening of regulatory standards will not lead to a shortage of specialised rolling stock,' Sergey Tereshkin, General Director of Open Oil Market, noted in a conversation with Vgudok.
His position is supported by data on the actual share of 'chemical' wagons in total petroleum transport volumes.
'Currently, less than 1% of oil‑related cargoes are transported in chemical tank cars: predominantly petrol and diesel fuel. Given the current situation in the freight transport market, this will not have any significant effect on the overall network fleet balance,' says Alexander Kotov, Partner for Consulting at NEFT Research.
Amid a decline in total loading on the Russian Railways network – for the first four months of 2026 the drop was 1.9% to 363.7 million tonnes – the question of efficient utilisation of surplus fleet becomes strategic. The Ministry of Transport's initiative aims to clear the infrastructure of morally obsolete rolling stock. At the same time, it is important to note that the state retains the possibility of operating specialised wagons for particularly dangerous cargoes, where there is truly no alternative, which demonstrates the balanced nature of the authority's approach.
For wagon owners, the coming changes are a signal to review investment programmes. The era of 'second life' for tank cars that have undergone multiple modernisations is coming to an end. From 2027, the only legal path for operators will be to acquire new rolling stock.
It is clear that such measures will not cause upheaval in fuel logistics, but they will create clear and transparent rules of the game in which safety and the interests of Russian wagon builders become the priority.
