ABSTRACT
The article discusses on the application of neodymium yttrium aluminum garnet (Nd:YAG) laser in gaining back the traction and electrical contact between the train and the rail that were lost due to the trapping and crushing of falling leaves in Great Britain. LaserThor company has investigated on the suitability of mounting Nd:YAG laser under the trains which would optically pump using laser diodes to remove the leaf residue from the rail as well as grease and rust. INSET: Rail debris.
