Prototipe kereta peluru tercepat di dunia, CR450, dengan kecepatan uji coba hingga 450 km per jam dan kecepatan operasional 400 km per jam, sedang menjalani uji tipe (type test) di jalur kereta lingkar Beijing untuk layanan komersial di masa depan.

Beijing, China (Xinhua/Indonesia Window) – Prototipe kereta peluru tercepat di dunia, CR450, dengan kecepatan uji coba hingga 450 km per jam dan kecepatan operasional 400 km per jam, sedang menjalani uji tipe (type test) di jalur kereta lingkar Beijing untuk layanan komersial di masa depan.

Kereta baru ini memulai debutnya di Beijing pada 29 Desember 2024. Moda transportasi tersebut secara signifikan lebih kencang dari kereta cepat CR400 Fuxing yang saat ini beroperasi dengan kecepatan 350 km per jam.

Wang Feng, wakil presiden CRRC Corporation Limited, produsen CR450, menekankan bahwa kereta tersebut menunjukkan lompatan menyeluruh dalam hal teori, teknologi, peralatan, standar, dan manajemen operasional kereta cepat, lapor harian Science and Technology Daily pada Kamis (6/3).

Untuk mencapai kecepatan operasional 400 km per jam, angka yang belum pernah tercapai sebelumnya, para engineer meningkatkan kapasitas traksi, kinerja dinamis, dan sistem pantograf, jelas Wang.

Kereta ini menggunakan sistem traksi magnet permanen berpendingin air, bogie generasi baru dengan stabilitas yang tinggi, serta inovasi multisistem untuk menopang operasi berkecepatan tinggi, papar Wang.

Keselamatan didukung oleh teknologi kendali pengereman darurat multilevel dan lebih dari 4.000 sensor pemantau di dalam kereta. Sistem keselamatan ini memeriksa sistem-sistem utama, termasuk roda gigi, bodi gerbong, pantograf tegangan tinggi, kendali kereta, dan sistem deteksi kebakaran, secara waktu nyata (real time). Sistem over-the-horizon juga meningkatkan deteksi situasi darurat di jalur kereta, lanjut Wang.

Terkait penghematan energi, desain penutup mesin (cowling) yang ramping pada bogie secara signifikan mengurangi hambatan udara, sementara teknologi dan material ringan baru mengurangi bobot kereta sebesar 10 persen dan menurunkan hambatan laju sebesar 22 persen, kata Wang.

Teknik pengurangan kebisingan semakin membedakan model ini. Tujuh teknologi inovatif, termasuk bahan penyerap suara dan bentuk aerodinamis yang dioptimalkan, mengurangi kebisingan kabin hingga 2 desibel, sehingga menawarkan perjalanan yang lebih tenang dan mulus bagi penumpang, tambah Wang.

Selain itu, upgrade yang cerdas membuat CR450 dapat mengungguli model lain di berbagai bidang, seperti operasi dan kendali, interaksi pengemudi, pemantauan keselamatan, serta layanan penumpang, imbuhnya.
