This depends on assets they have access to, at a global financial market level "power industry" has more funds available to them than "railways industry", because of focus in energy efficiency and greater interest in non-fossil fuel related electricity generation and transmission these days. No asset management company can live outside of market economics.
just going by wiki PFC and IRFC seems to be at par, subject to assets they have access to.
if the argument is that IRFC needs to expand by utilising more railway assets, then
YES.
if the argument is that everything is crap because i feel so, then
NO.
