Design capabilities, speed program, speed effects, cross and vertical sections of the existing lines, alterations, additions of second-line plane, longitudinal and cross-sectional design.

Design capacity, speed, and speed programs, both on the flat 縱斷面 alterations, additions, and 2-Wire flat and 縱斷面 transverse to the design.

Designed capacity, puts forward the fast plan, raises aspects and so on fast effect, to already the wired even longitudinal section reconstruction, additionally constructed two planes, the longitudinal section as well as the cross section has carried on the design.

Aspects of programme design capabilities, speed, speed-increasing effect, profile alteration to the existing line, the second line of planes, longitudinal section and cross design.
