A beveled-end steel railroad. The use of small-acute-angle oblique-gap connection design and vertical gap reservation design can solve both the problem of impact between wheels and rails and the problem of thermal stress between steel rails. The design containing both beveled ends and flat ends that are complementary to each other can further greatly reduce railroad construction and reformation costs. The beveled-end steel railroad has a simple structure, is secure, reliable, and durable, can provide a fast, stable, and non-noisy driving effect, can implement highly-efficient and energy-saving operation, is easy to construct and reform, can be easily repaired and maintained, has a significant advantage in costs, and can implement both good performance and good profitability.

A surface-seamless steel rail is provided in the present invention. Said surface-seamless steel rail includes a right connecting part located on one side of said steel rail, a left connecting part located on the other side of said steel rail, and a seamless spring piece located on the top side of said steel rail. Both said left connecting part and said right connecting part include a plug portion in embedded engagement with each other. Said seamless spring piece includes a fixed portion at one end and a free portion at the other end, said fixed portion is fixedly connected on top side of said plug portion of one of said left connecting part and said right connecting part. The other of said left connecting part and said right connecting part is provided with an arc-shaped channel at its interior body, said free portion of said seamless spring piece is suitably inserted into said arc-shaped channel.
