Practical trials with plasma torch may enable adhesion values of 0.3 to be regarded as standard; 99% of adhesion values measured are within 0.2 to 0.6 when rails are dry, and 0.1 to 0.4 when rails are wet; it has been known for some time that high powered pulsed arc between electrode on locomotive frame and rail head will improve coefficient of adhesion; to overcome defects of electric arc onto rail head, British Railways Research Dept has examined d-c excited plasma jet.
