THIS refers to Dr J. Effendi’s letter ‘Solution to CNG crisis’ (Nov 16). The writer has given a good proposal to give some relief to public transport running on CNG. It is a good idea to make separate CNG stations for public transport and private vehicles to reduce mad rush and long queues at CNG stations.

I agree with the proposal and would like to add that in addition to having separate CNG outlets located at convenient places for commercial and public transport vehicles, these outlets should be closed for lesser duration than those meant for private vehicles, say for one day instead of two.

It is very important that CNG use should not wither away because it is not only more economical than petrol and diesel but also much more environment-friendly. That is why its use is encouraged in rich, advanced countries where public transporters can easily afford to use petrol and diesel. A number of taxi cabs and public transport vehicles run on liquefied gas in the US, Canada, Italy and Japan in order to save the environment from pollution.

Closure timings I ENDORSE the suggestions given by the writer in the Nov 16 letter. In addition, I will suggest that, in order to avoid traffic jams and hurdles on main roads due to queues by the vehicles to fill the CNG, the closure timings should be midnight instead of 9.00pm for a smooth flow of traffic.
