Over 200 Home-Made Parts Used in Iran’s Subway System
Hojjatollah Qa’ed Rahmati, the deputy director-general of the Tehran and Suburbs Subway Operating Company, described indigenization of rail transportation as a strategic step towards self-sufficiency and sustainable development, and said, “The rail transportation industry, specially the subway, as one of the vital arteries of the capital, needs indigenization of parts and equipment more than ever.”
He underlined the possibility for manufacturing another 198 parts inside the country, and said, “The Tehran and Suburbs Subway Operating Company, relying on the capabilities of the Iranian experts and close cooperation with the knowledge-based companies, has so far taken effective steps towards indigenization of parts.”
In a relevant development in 2024, Iranian experts at a technological company had reverse-engineered two widely-used measuring tools used at Tehran's subway to monitor the wheels of trains.
“Our newest device is a diameter gauge and a compound caliper, which were reverse-engineered and produced at the request of Tehran’s subway,” said Hesamoddin Davoudinejad, the head of the company's commercial department.
Noting that the device is a tool for measuring the diameter of the wheels and the thickness of the flanges of the wheels of trains, he said, “Since these tools are used in servicing the trains, they are subject to breakage and damage, and re-purchasing them from a foreign country requires a lot of money."
“At our company, we have started manufacturing a diameter gauge and a compound caliper at a quarter of the cost of the foreign model. The measurement accuracy of our product is similar to the foreign model,” Davoudinejad said.
“A compound caliper is a combination of two calipers and measures the thickness of the wheel flange,” he explained.
