there can be huge variations in some trains and as such blog looks totally out of place
one more example
suppose train nuber 99999 runs from a to b with speed 30 kmph
we post blog that this train speed is so slow like tortoise
....
more...

some 20 days later, suppose 99999 train gets cancelled from a to b and now run from a to c with speed 85 kmph
.
now the original blog still says that train speed is like a tortoise and some new blogger can ask uestion that how can you say its a tortoise with speed 85 kmph.....
....
then that gets really irritating to explain all the changes....
