Abstract This paper is a continuous part of the thesis “Integral Continuity of Railway in West Europe” written by the author，which was issued in No. 4 of the“Journal of the Railway Engineering Society”in 1998. In this paper，the following articles are introduced；the influence factors of the longi?tudinal force on jointless rail on bridge in railways of West Europe and its calculating method, the maximum span of bridge having jointless rail on bridge without expansion joints,measures for reduc?ing the additional forces, track structure, new concept on expansion joints,etc. As the design princi?ples for jointless rail on bridge by UIC are introduced,the author points out especially the important meanings concerncd with the ultimate value of additional forces (including tension and compression) .the ultimate value of the relative displacement of rail on bridge beams.the maximum span of simply supported bcam without expansion joints，etc.
