It may be the case that such schemes cannot operate unless some people make a substantial sacrifice for them.

Some schemes operate stations across an entire city, serve members only, and are targeted to commuters.

The scheme operates both an adult and junior series of awards.

The scheme had operated for nearly three years but came to light only in the past year.

The scheme is today in a bad state and only operated with a voltage of 100 kV.

Both schemes have been operating since 2002 and are due to authorise their final grants by the end of the year.

If the user is not an Administrator at all, a similar scheme operates.

The scheme operated for at least 13 years, the indictment said.

In the first place, the scheme only operates for five years, with no guarantee of continuation.

My interest is in the practical way in which the scheme will operate.
