` -> This is an H2, not the main title tag equivalent, but usually, the first H2 serves as the headline in these contexts. However, the prompt mentions “ORIGINAL TITLE” and “CURRENT SEO GAPS” regarding title length. The current H2 is quite long. Let’s check the character count: “Preparing Europe’s Railways for a Warmer Tomorrow: Eurostar’s Celestia Fleet Upgrade” is roughly 85 characters. It needs to be shorter. * **Keyword:** “Why Eurostar s new Celestia”. * Current mentions: 1. “Why Eurostar s new Celestia trains – Across…” (Para 1) 2. “The decision involves upgrading the new Celestia trains…” (Para 1) 3. “The Celestia trains, which Eurostar confirmed…” (Para 3) 4. “equip our new fleet of up to 50 Celestia trains…” (Blockquote) 5. “Beyond the thermal upgrades, the Celestia trains…” (Para 8) 6. “the Celestia trains will introduce…” (Para 8) * Wait, the prompt says “21 keyword-term mentions” in the *current* rewrite.

Perfect. 5. **Refining the Text:** * *Title:* Why Eurostar s new Celestia trains need heat upgrades * *Para 1:* Why Eurostar s new Celestia trains are undergoing a crucial transformation is the changing climate. As Europe faces hotter summers, the rail operator is enhancing its fleet. The new rolling stock will now withstand 55 degrees Celsius, up from the original 45 degrees. * *Para 2:* This adjustment ensures longevity for the service running from 2031 to the 2060s. Recent heatwaves have shown that standard cooling systems struggle under extreme pressure. By upgrading the air conditioning, Eurostar aims to prevent future disruptions caused by thermal stress. * *Heading:* Technical Enhancements for Extreme Weather * *Para 3:* The Celestia fleet consists of 50 double-decker trains built by Alstom. Originally designed for moderate climates, the updated specifications allow them to operate reliably in record-breaking heat. France recently recorded 44.3 degrees in Pissos, highlighting the need for such robust engineering. * *Para 4:* Passengers will benefit from consistent interior temperatures regardless of external conditions. The enhanced systems address both mechanical strain on tracks and electrical components. This proactive measure secures the reliability of cross-channel travel for decades to come. * *Blockquote:* “A decision has been taken to equip our new fleet of up to 50 Celestia trains with air conditioning capable of operating in temperatures up to 55 degrees,” a Eurostar spokesperson explained. “These trains will enter service in 2031 and run into the 2060s so it’s essential to be prepared for the future.” * *Heading:* Expanded Network and Economic Benefits * *Para 5:* Beyond thermal resilience, the Celestia trains offer increased capacity. Each unit holds 540 passengers, a 20 percent rise over previous models. They will connect five countries and introduce new routes to Geneva and Frankfurt, supporting Eurostar’s goal of 30 million annual passengers. * *Para 6:* The operator contributes £2 billion to the UK economy annually.
