One of the indicators of -76- under development in this country is the backward state of the transport sector. This is typified by the poor state of the railway -77-. In advanced countries, commuter trains carry passengers from city and within suburbs. The -78- train goes a lot faster connecting major cities and even states; such trains have -79 only. In the intra- city trains, it is only shelter and seats that are provided. There are no -80-. In some cases, and because of the long hours of service of inter-city or inter-state trains, -81- and -82- are available in addition to coaches. Apart from the very fast electric trains, there are passenger trains that are -83- powered. There are others that use coal or steam as -84-. Some trains offer -85- services, transporting goods. Such trains stop at specific -86- to deliver goods or to refuel. Most trains have -87- to push or pull them to prevent them from turning around.

Before the end of the second month, we realized it was not going to be a -97- but a storeyed building. The -98- was cast in only one day by the workers who -99- for the whole day. Thereafter things moved even faster. By the end of the third month, the whole -100- was in place.
