This is a busy and crowded route. Bus number 117 comes once in 20 mins which is not sufficient to meet the needs of so many people especially school children and office goers. Moreover Oyster card does not work on trains beyond Feltham, and so most people travel by bus. Plus it is not even a double decker bus to accommodate so many people. The buses are so jam packed due to poor bus frequency, that many times the bus does not stop at certain stops as the bus is too full. So the passengers have to wait for another 20 mins for the next bus 117. We need a bus at least once every 10 mins, to be able to cope with the passenger rush.
