In this study, I show several time maps using new concepts, and discuss their usefulness. For showing examples of time maps, I pick up the times required by railways of the Eurasia Continent.　As usual, For making time maps, the multi-dimensional scaling method was applyed, which was proposed by Torgerson 1952. However, this method has two problems. One is that, we can hardly understand the true times required from the time map, and the other is that the topological structure is often broken in the time map by that method, hence we sometimes mislead the time map. I focus on the former problem and propose new time maps.　I consider time maps based on the multi-dimensional scaling method. Then, I show two new ideas of time maps which partially indicate exact times required (between several cities). These time maps are worth using because the precision of them are as not being inferior compared with the time map using the multi-dimensional scaling method.　Futhermore , I show simple shape time maps which are one dimension type, elliptic type, and 8 character type. These time maps are valid for evaluating the transeportation network and effect of new railways.
