Oh dear. You would think if you were going to spend millions on ordering trains you would at least get the measurements right. I think something very similar happened in France a couple of years ago. They had to rebuild some platforms and space out some tracks in order to use the trains.I have been getting news feeds about trains ordered for the Spanish regions of Asturias and Cantabria being too big to fit in their tunnels. Can anyone add any detail/thoughts on this?
Two Spanish transport executives have been fired after a train fiasco that saw the design of 31 trains that were too big for the tunnels on the line where they would run.
Spain recently spent €258m (£228m) in designing 31 trains that will be delayed by several years due to a major design flaw.
The train designs were meant to be used in the FEVE line, which runs through the areas of Asturias and Cantabria. This line dates back to the 19th century, and so its tracks have track gauges narrower than the standard 1,435mm (4ft 8.5in), something that the manufacturer failed to notice in the designs.
Renfe, Spain’s national rail operator, Adif, the track company, and the country’s Left-wing coalition government have all faced harsh criticism after failing to notice the design fault.
CAF, the Basque manufacturer in charge of the construction of the trains, first raised concerns about the sizing in March 2021. The company had signed a €258m (£228m) contract in June 2020 to build 31 trains - 30 for Cantabria and 10 for Asturias - by October 2024.
The mistake was spotted before any train was constructed but it has delayed the delivery of the project by several years. The trains will now likely arrive in 2026.
The Ministry of Transport has commissioned an internal audit, while Renfe revealed that its rolling stock manager had been fired along with the head of Adif’s technology inspectorate.
The root of the problem seems to relate to a Declaration of the Network statement published by Adif in 2019 and used by Renfe to describe the technical characteristics of the new trains. However, the document did not describe the gauge of railway lines.
“The problem is that the ‘official’ measurements of the tunnels do not correspond to reality,” a Renfe spokesperson said.
However, Adif argued that it is not responsible for errors in the contract specifications by Renfe.
Sources in the railway sector told El Español that “it seems that Renfe interpreted that the standard gauges of the Gauges Railway Instruction are those existing throughout the network, without realising that they are the ones applied in new and refurbishment works.”
In order to address the issue, officials have said they will use the “comparative method”, which relies on using a train already circulating on the network as a reference for the size of the new designs.
This solution has been used successfully in the UK in the past, but never in Spain, which means it will require the authorisation of the Spanish railway safety authority.
Pedro Sánchez, Spain’s president, said he only found out about the problem “shortly before it was public knowledge” and that he had taken immediate measures to address it.
However, the government’s infrastructure secretary, Xavier Flores has admitted to knowing about the issue for several months.
“It was the first time that we were faced with buying a train on this line,” he added.
Miguel Angel Revilla, the president of Cantabria, who has long complained of poor transport infrastructure in his region, described the mix-up as an “outrageous botch-up”.
“When a project is launched, one assumes the company in charge knows what it has to provide,” he said. “If it is a train, it has to know the width of the wheels and if the train has to go through a tunnel.
“Someone has to pay for this and we need those trains now because one of the biggest issues in this region [is that] our trains are from the Wild West era,” he added.
The two years between the signing of the contract and the change in strategy have been said to have been spent in “technical discussions”, although the Spanish government has said it considers the process has not been “diligent enough”.
The trains must now be redesigned to ensure they can pass safely through tunnels on their intended routes. Both companies have committed to cooperate with the audit of the Ministry of Transport with absolute transparency.
You should have seen the list of restrictions for the 80Xs when they first came in.Oh dear.

...Various parties played a part in the debacle, including Spain’s national rail operator Renfe, rail infrastructure manager Adif, transport manufacturer CAF and the State Agency for Railway Safety (AESF).
After granting the manufacturing contract to CAF, Renfe says it provided measurements based on infrastructure specifications provided by Adif. CAF later warned that the specifications may not be correct...
Because journalists don't understand the difference between track gauge and structure gauge. A decent explanation is hereI'm getting confused. Most of the articles quoted the trains are too big for the tunnels which implies the width or length of the carriages is too big, but one comment says that the track guage (the gap between wheels on the same axle) was wrong. Which is correct?
The Euro 4000 locomotive was designed to operate throughout Europe and is 4,264 millimetres (13 feet 11+7⁄8 inches) high above the railhead. During the tendering and negotiating process, PRASA submitted a loading gauge specification which called for a maximum height of 4,140 millimetres (13 feet 7 inches). Since the latter height was feasible by only modifying the detachable roof structures and some components without affecting the carbody structure or requiring major modifications, Vossloh España proceeded with the locomotive design once the contract was signed.[19][20][21]
The Transnet Freight Rail loading gauge specification which had been submitted during the tender phase when only the Euro Dual electro-diesel locomotive was being considered in the scope of the contract, was one which made special allowance for the pantographss on electric locomotives to exceed the actual maximum height of 3,965 millimetres (13 feet 1⁄8 inch). The loading gauge specification for diesel-electric locomotives and other rail vehicles, specifying a maximum height of 3,965 millimetres (13 feet 1⁄8 inch) above the railhead, was submitted to the manufacturer in October 2013 after the locomotive design was completed. The two loading gauge versions are identical in respect of roof profile and height, and differ only in respect of the special provision for the pantographs on electric locomotives to exceed the prescribed maximum height.[19][20][21]
Since reducing the locomotive height to 3,965 millimetres (13 feet 1⁄8 inch) would require a complete re-design of the vehicle equipment and the carbody structure and since the Afro 4000 locomotive, as already designed, would fit into the first submitted loading gauge for electric locomotive pantographs, PRASA accepted the locomotive design at the 4,140 millimetres (13 feet 7 inches) height.[19][20][21]
Most of this text is hack drivel. Building of the lines in question wasn't started until 1921, and wasn't fully completed until 1972...Spain recently spent €258m (£228m) in designing 31 trains that will be delayed by several years due to a major design flaw.
The train designs were meant to be used in the FEVE line, which runs through the areas of Asturias and Cantabria. This line dates back to the 19th century, and so its tracks have track gauges narrower than the standard 1,435mm (4ft 8.5in), something that the manufacturer failed to notice in the designs.

This was a hoax which was debunked ages ago.Noting that they are only in the design phase, it's not like France when they were built before the oversize issue was found out. A slightly non-story really.
It wasn't just the Electrostars the desiros on dc were even worse.To be fair to our continental friends, when we ordered the electrostars, we had to swiftly upgrade the electricity supply in Southern England to cope with them !
seems wrong.It was the first time that we were faced with buying a train on this line,
This was known about before specification though, plans had already been made to fix this.The 95 Tube stock was too big for some of the Northern Line tunnels albeit marginally
As station staff we didn't know about that. all we knew was they were too big and was going to be done to make the tunnels biggerThis was known about before specification though, plans had already been made to fix this.

Two top Spanish transport officials have resigned over a botched order for new commuter trains that cost nearly €260m ($275m; £230m).
The trains could not fit into non-standard tunnels in the northern regions of Asturias and Cantabria.
The head of Spain's rail operator Renfe, Isaías Táboas, and the secretary of state for transport, Isabel Pardo de Vera, have now left their roles.
The design fault was made public earlier this month.
The Spanish government says the mistake was spotted early enough to avoid financial loss. However the region of Cantabria has demanded compensation.
Renfe ordered the trains in 2020 but the following year manufacturer CAF realised that the dimensions it had been given for the trains were inaccurate and stopped construction.
The rail network in northern Spain was built in the 19th Century and has tunnels under the mountainous landscape that do not match standard modern tunnel dimensions.
The mistake means the trains will be delivered in 2026, two years late.
Renfe and infrastructure operator Adif have launched a joint investigation to find out how the error could have happened. Earlier this month, Spain's transport ministry fired a Renfe manager and Adif's head of track technology over the blunder.
The Socialist-led coalition government of prime minister, Pedro Sánchez, has tried to make further amends by announcing that travel on the Asturian and Cantabrian networks affected by the delays would be free until the new rolling stock began to come into service in early 2026
You should have seen the list of restrictions for the 80Xs when they first came in.
It doesn't entirely add up, I agree. If CAF noticed before they did any work, why are they delayed by two years? Some of this does seem to be purely politics though - there are elections this year so more is being made of this than might be the case at another timeI find it difficult to believe that "no Spaniard's money has been wasted".
CAF will want paying for the abortive design and development work to date, at the very least.
Renfe and Adif will also have to redo the train specification.
In the Guardian version of this report, it says fares will be free on the affected network until the new trains arrive.
