	%X Railways in India remain primary mode of transport
having one of the largest networks in the world and catering to
billions of transits yearly. Catastrophic economic damage and loss
to life is encountered over the past few decades due to fire to
locomotives. Study of fire dynamics and fire propagation plays an
important role in evacuation planning and reducing losses. Simulation
based study of propagation of fire and soot inside an air conditioned
coach of Indian locomotive is done in this paper. Finite difference
based solver, Fire Dynamic Simulator (FDS) version 6 has been
used for analysis. A single air conditioned 3 tier coupe closed to
ambient surroundings by glass windows having occupancy for 8
people is the basic unit of the domain. A system of three such
coupes combined is taken to be fundamental unit for the entire
study to resemble effect to an entire coach. Analysis of flame and
soot contours and concentrations is done corresponding to variations
in heat release rate per unit volume (HRRPUA) of fire source,
variations in conditioned air velocity being circulated inside coupes
by vents and an alternate fire initiation and propagation mechanism
via ducts. Quantitative results of fractional area in top and front
view of the three coupes under fire and smoke are obtained using
MATLAB (IMT). Present simulations and its findings will be useful
for organizations like Commission of Railway Safety and others in
designing and implementing safety and evacuation measures.
