 note = {For the purpose of investigating the air flow when a train runs into a tunnel, the authors
of this paper simplified the problem as stated in the former report and investigated the
air velocity in the inlet and outlet of the pipe by moving short columns into the horizontal
pipes.
Hara has studied about the air pressure when the train runs into the tunnel in case of
changing the top shapes of the train, but nothing seems to be investigated about the air
velocity.
Then, in the present paper, we report about the air velocity in case of changing the
shape of the top and back of the columns.
On the other hand, we state about the air velocity in case of the high speed of the
column corresponding to that of the train.},
