Effective 1 January 2027, the Ministry of Transport will impose a complete ban on the use of upgraded tank cars that were previously life-extended for chemical cargoes but later used to transport petroleum products. This initiative aims to eliminate the "grey" schemes for extending the service life of rolling stock that emerged during the railcar manufacturing crisis of 2015–2016. We examine how this decision will affect fleet balance and the fuel market.
The transport ministry is preparing to fundamentally rewrite the rules of the rail freight market by closing a regulatory loophole that has allowed age‑expired tank cars to operate for decades. According to a draft order dated 6 May 2026, from 1 January next year a full ban will be placed on including in trains any upgraded tank cars that were previously life‑extended for specialised chemical cargoes.
The roots of the current situation go back to 2015–2016, when Russian railcar manufacturing was in deep crisis and production volumes of freight rolling stock fell by more than 54%.
At that time, to support the factories, the state introduced restrictions: it banned the life extension of mass‑type rolling stock, including gondola cars and tank cars.
However, the market quickly adapted by finding an exception in the technical operation rules (PTE). 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 preserved.
In practice, this led to the emergence of "grey" schemes. Owners of rolling stock carried out modernisation of tank cars under the "chemical" specialisation, which allowed them to legally operate the old fleet. The main tool was repair at foreign facilities, for example at the Kazakh enterprise "Ak‑Zhaiyk‑7". The technological process made it possible to expand the list of permitted cargoes from a couple 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 transportation of petrol and diesel fuel, competing with owners of new rolling stock.
In the winter of 2026, the problem reached the ministerial level. At that time, the head of the wagon management department of the Central Infrastructure Directorate of Russian Railways, Roman Khoykhin (subsequently detained by security forces – read more HERE), wrote to Deputy Minister of Transport Alexey Shilo pointing out the ambiguity of the PTE: the rules allowed modernisation of the wagon type but did not restrict the nomenclature 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. Now, however, the ministry has decided to change its position, moving from controlling the contents 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. At JSC Russian Railways and the Union of Wagon Builders, they stress that the need for such "exceptions" has disappeared. According to estimates from the Union of Wagon Builders, in 2026 the industry is ready to produce 12,000–15,000 new tank cars, which more than covers the write‑off of 8,300 old units. The ban on "chemical" extensions, in the opinion of industry players, will remove barriers to the emergence of new innovative models and ensure even loading of factories.
The question of how this will affect fleet balance remains key. According to official data, just over 450 "extended" tank cars are operating 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 can operate on the Russian Railways network. This means cargoes can be carried in wagons as long as their age is less than that specified in the manufacturer's design documentation. This was implemented by including in the PTE a clause prohibiting the inclusion in trains of wagons for which, after 1 January 2016, work to extend the designated service life had been carried out, says Alexander Polikarpov, Managing Partner and co‑founder of ROLLINGSTOCK Agency.
"There were a number of exceptions to the general rule, in particular for wagons that were not produced in Russia at that time, or those that were needed for state transportation. In the tank car segment, extensions were conditionally allowed for models carrying yellow phosphorus, wine materials, heptyl, amyl, acetic acid, pesticides, alkylbenzenesulphonic acid, melange, milk, polyvinyl chloride, caprolactam, superphosphoric acid, and sulphanol.
In 2025, the service life of a batch of oil‑petrol tank cars was extended by carrying out modernisation under the accounting specialisation of 'pesticides'.
These tank cars, according to the documentation, could also be used to transport a wide range of cargoes, including oil products. After modernisation, the extended wagons were used to carry petroleum products. Thus the ban on extending the life of oil‑petrol tank cars was circumvented.
Now the Ministry of Transport is closing the discovered loophole with new changes to the PTE. In the new version of the Technical Operation Rules, the possibility of extension is preserved only for tank cars carrying heptyl and melange. It should be noted that this change will not significantly affect the balance of the tank car fleet," the expert believes.
Other market participants also urge not to dramatise the situation, pointing out that the logistics of petroleum products are determined by other, much more significant factors.
"The need to renew the tank car fleet for petroleum product transportation will not strongly affect the fuel market, for which a more important role is played by other factors: the volume 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 can also include rail freight tariffs for petroleum products.
Against this background, issues of tank car fleet renewal are a secondary factor, especially since, as a number of experts believe, the tightening of regulatory norms will not lead to a shortage of specialised rolling stock," noted Sergey Tereshkin, General Director of Open Oil Market, in conversation with Vgudok.
His position is supported by data on the actual share of "chemical" wagons in the total volume of oil transportation.
"Currently, less than 1% of oil cargoes – mainly petrol and diesel fuel – are carried in chemical tank cars. Given the current situation in the freight transport market, this will not have any significant effect on the overall network fleet balance," said Alexander Kotov, Consulting Partner at NEFT Research.
Against the backdrop of a decline in overall loading on the Russian Railways network – in the first four months of 2026 the drop was 1.9% to 363.7 million tonnes – the issue of efficient utilisation of the excess fleet becomes strategic. The Ministry of Transport's initiative is aimed at clearing the infrastructure of morally obsolete rolling stock. It is important to note that the state is retaining the possibility of operating special wagons for particularly dangerous cargoes, where there truly is no alternative, demonstrating the balanced approach of the ministry.
For wagon owners, the upcoming changes are a signal to review investment programmes. The era of a "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 upheavals in fuel logistics, but they will create clear and transparent rules of the game in which traffic safety and the interests of Russian wagon builders become the priority.
