Takeaways

• 🚄 The Renfe 252 series locomotives played a key role in the early years of the Madrid-Seville high-speed line, inaugurated in 1992.
• 🏗️ The 252 series was derived from the 269.6 locomotives, with design improvements for high-speed operation.
• 🇩🇪 The first units were built by Krauss-Maffei in Germany, with the 252002 being the 20,000th locomotive produced by the company.
• 🎨 Initial decorations of the locomotives were yellow-gray with the Ave logo, later standardized to a white-black high-speed Spanish logo livery.
• ⚡ These locomotives were designed for both international and Iberian gauge tracks, with 15 units of international gauge and 60 of Iberian gauge produced.
• 💨 The 252 series could reach a maximum speed of 220 km/h in tests, though operational speeds were limited to 200 km/h.
• 🛠️ Technical specifications include Bo′Bo′ bimotor bogies, 1250 mm wheel diameter, 5600 kW nominal power, and 29,571 kg continuous tractive effort at 70 km/h.
• 🚆 The locomotives primarily hauled Talgo 200 trains, capable of variable gauge operation, and complemented AVE series 100 trains.
• 🌍 The 252002 toured Europe for exhibitions and demonstrations, highlighting its significance in international railway history.
• 👨‍✈️ The interior and cab design of the 252 series offered high comfort and advanced technology for train drivers, surpassing other Spanish locomotives of the early 1990s.
• 🖼️ Some locomotives featured dual logos and participated in high-speed tests, including runs that reached 300 km/h during trials.
• 📈 The 252 series helped establish the operational and technical foundation for Spain’s modern high-speed rail network.

Q & A

What is the main focus of the transcript?

The transcript focuses on the Renfe 252 series locomotives, particularly the 252002 unit, their history, technical specifications, and their role in the Madrid-Sevilla high-speed rail line.

When was the Madrid-Sevilla high-speed line inaugurated?

The Madrid-Sevilla high-speed line was inaugurated on April 20, 1992.

What type of trains did the 252 series locomotives pull on the high-speed line?

The 252 series locomotives pulled Talgo 200 trains, which were modern trains capable of speeds up to 200 km/h in regular service.

What was the origin of the 252 series locomotives?

The 252 series locomotives originated from the Renfe 269.6 series, which were tested for high-speed service in the late 1980s. Later, Germany's Krauss-Maffei built the Eurosprinter-based 252 locomotives.

How many 252 locomotives were built for international and Iberian gauge tracks?

Fifteen locomotives were built for international gauge (1435 mm), and later the series expanded to sixty units for Iberian gauge (1668 mm).

What were the speed capabilities of the 252 series locomotives?

Technically, the locomotives could reach 220 km/h with the LZB system, but in service they were limited to 200 km/h.

What are some key technical specifications of the 252 series locomotives?

They had 4 traction motors of type TV 2824, a continuous power of 7,616 hp (5,600 kW), weight in working order of 90 tons, a wheel diameter of 1250 mm, and could operate under 25 kV AC or 3 kV DC.

What was unique about the 252002 locomotive?

The 252002 locomotive was the 20,000th unit produced by Krauss-Maffei, toured Europe for exhibitions, and initially had a yellow-gray livery before receiving the standard white-black high-speed paint.

Why did Renfe decide to order locomotives from Germany instead of Japan?

Renfe was not satisfied with the Japanese Chopper locomotive tests, so they chose German engineering to develop high-speed locomotives capable of 220 km/h for Talgo 200 trains.

How were the Talgo 200 trains designed to adapt to different rail networks?

The Talgo 200 trains could change track gauge using strategic gauge changers and switch from 252 locomotives on high-speed lines to 269 series locomotives for conventional tracks.

What features made the 252 series locomotives advanced for their time?

The 252 series offered a modern, comfortable cab, advanced traction technology, multi-locomotive control, electric train heating, and high-speed capabilities that surpassed earlier Spanish locomotives.

What role did the 252 series locomotives play in Spanish rail history?

The 252 series was a symbol of Spain's early high-speed rail era, contributing to the operation of Talgo 200 and AVE trains, marking technological advancement in both domestic and international rail networks.
