This logo is unique in that the upper part is similar to the rails and the grid on the train, all this is combined with the letter M, which means the subway, you can continue the logo, and it will be in the text version, or in what is now.

In addition, the entire logo is slightly elongated in 3D for the shadows, because it is too flat without shadows, you can choose any color, I chose slightly red CMYK, this is good, with the logo comes,patern,fonts and everything you need to work.
