bunk a narrow bed fixed to the walls of a compartment in a train
buzz sound made by a flying insect
compartment a part of a passenger train in which there are seats or sleeping space
doze sleep lightly for a short time
force of habit done without thinking
itch to have a tickling feeling
porch a roofed place outside the entrance
rumble to make a deep rolling sound
scratch 1. to mark with something sharp 2. to rub where it itches
screech a loud, high-pitched sound
snarling growing
whimper to cry softly
wink to close and open one eye quickly
