on street unsegregated operation, as now, may be considerably

improved, perhaps to an acceptable level. Operations through

this area need not be fast, but they must be reliable if the

efficient operation of the Central tunnels and the remainder

of the LRT system is not to be prejudiced.

There would appear to be no intrinsic difficulty in integrating

an LRT Route into a redesigned Connaught Road West improvement

though it could not be achieved until about 1982. Initially,

the service might lose some traffic because it lies some distance

away from the principal existing traffic generators, though this

might be offset by the higher speed and greater reliability of

service on the new alignment. In the longer term, additional

traffic will be generated by the new land uses located on the

adjacent reclamation.

Tunnel construction is difficult in Western: the narrow street

widths have required the proposed MTR stations, for instance, to

be constructed with one line vertically above the other, rather

than in the usual less expensive side-by-side manner.

It would

appear however, that side by side construction could be possible

in Des Veoux Road West, provided rolling stock width was no greater than 2.5m (compared with 3.0m of MTR).

At this stage rather than reach a specific conclusion on which

LRT alignment would ultimately be required between Western Market and Whitty, it seems more appropriate to have a policy which

commences with on-street operation in Des Voeux Road West, but

keeps open the alternatives of a Connaught Road West alignment or

a tunnel along Des Voeux Road West, if satisfactory on-street

operation cannot be acheived. The flexibility on an LRT system

allows such a policy to be persued.

Chaiwan Extension The Chaiwan extension is important, not only because Chaiwan is a rapidly developing area which will produce

an above average increase in travel demand but also because of

the usefulness of an extension for access to the depot site.
