HC Deb 20 March 1939 vol 345 c906
50. Mr. Kirby

asked the Minister of Health whether the London Midland and Scottish Railway Company have yet started their series of experiments in methods of firing locomotives; if so, what are the nature and results of such experiments; and what effect has been produced towards mitigating the smoke nuisance in the central area of Liverpool?

The Minister of Health (Mr. Elliot)

I am informed that these experiments are now in progress and are being carried out in conjunction with measurements by the Liverpool Town Council of the state of the atmosphere at tunnel openings. Until the experiments are completed it will not be possible to assess their result.
