		abstract={Double-Double Track railway lines is number two or more which aims to
separate the main line RAILWAY to long-distance and Commuter TRAIN lines
thereby eliminating delays in Commuter TRAIN and also simultaneously
increase capacity passenger now the 850 thousand passengers into 1.2 million
passengers per day.
Redesain structure of DDT began with the necessary technical data collection
such as dimension columns, beams, quality material and loads acting on the
structure of DDT. In the early stages of planning done modeling design of
rectangular columns and continued analysis of the load acting on the structure
Column K2. Then from the results of analysis carried out calculations of the
structure column K2 with dimensions different from the design of the original
plan, the work load analysis calculation used computer applications. The results
obtained the structure column that has the dimension of the cross section of
penulangan influence on the structure of the columns.
The final results are obtained in the form of a planning dimension column
1280m x 1280m, 68D32 main reinforcement, forces acting on the structure
column. Square column and more effective compared to rectangular column,
seen from the reduction against the vast room.}
