Old trams and trolleybus lines are progressively disconnected because of the poor service and high operation and maintenance costs. In most cities, public transport relies on buses, and the light-rail transit (LRT) networks suffer from serious lack of rationalisation. Delegation of communal services to the private sector will work only if the national government helps city governments modernise communal infrastructure. However, city akimats need to be more pro-active in finding ways to refurbish urban infrastructure.
