加快铁路建设是一项重要的任务，其中最核心的是什么？

首先，要加快铁路建设，必须加强规划。要根据国家发展战略和经济发展需要，制定合理的铁路发展规划，明确建设重点和优先级，避免盲目建设和重复建设。同时，要注重与其他交通方式的有机衔接，形成综合交通运输体系，提高铁路建设的整体效益。

其次，要加快铁路建设，必须加强技术创新。要积极推广应用新技术、新材料、新工艺，提高铁路建设的科技含量和竞争力。同时，要加强自主创新，研发出具有自主知识产权的铁路技术和设备，打破国外的技术垄断和封锁。

最后，要加快铁路建设，必须加强人才培养。要注重培养具有国际视野和专业技能的铁路建设人才，建立健全的人才培养机制和激励机制。同时，要加强与国际社会的合作与交流，吸引更多的国际人才参与中国的铁路建设。

综上所述，加快铁路建设的核心是加强规划、技术创新和人才培养。只有把握住这三个关键环节，才能推动铁路建设事业的快速发展。

What is the core of accelerating railway construction?

Firstly, to accelerate railway construction, planning must be strengthened. Based on national development strategies and economic development needs, reasonable railway development plans should be formulated to clarify construction priorities and give priority to avoiding blind construction and redundant construction. At the same time, attention should be paid to the organic connection with other modes of transportation to form a comprehensive transportation system to improve the overall efficiency of railway construction.

Secondly, to accelerate railway construction, technological innovation must be strengthened. We should actively promote the application of new technologies, new materials, and new processes to increase the technological content and competitiveness of railway construction. At the same time, independent innovation should be strengthened to develop railway technology and equipment with independent intellectual property rights, breaking foreign technological monopolies and blockades.

Finally, to accelerate railway construction, talent training must be strengthened. Attention should be focused on cultivating railway construction talents with international vision and professional skills, establishing sound talent training mechanisms and激励机制. At the same time, cooperation and exchanges with the international community should be strengthened to attract more international talents to participate in China's railway construction.

In summary, the core of accelerating railway construction is to strengthen planning, technological innovation, and talent training. Only by grasping these three key links can we promote the rapid development of railway construction.
