Transportation.

     Transportation is vital in our daily lives. Work or school - we just have to reach on time. In transportation, the differences between past and present are not that much. In the past, they have cars, motorbikes, buses, trains, bicycles and trishaw. Today, we still have these transportation. The differences are, buses and trains, nowadays, all are air-conditioned. Last time, people simply get fresh air from the open window of the buses or trains. Our buses nowadays, seems all are double-decked buses. The buses even have installation 'slopes' for the wheel-chair people to board the bus. For the SMRT trains, more railings are build so that passengers can simply grab onto the railings if seats are occupied.
