in switch case statement, don't worry about e1, e2 ,e3, ... and so on.
when we use normally 1, 2, 3, ...
and client is type like 53 get stuck at a infinite loop and crash
even though we use default: key word on last case,
so, we need two use something different for this issue
use enum!
and translate elements to numbers like this:

RailwayCli/main.cpp
