The line had been expensive to construct; the ''[[Railway Magazine]]'' described the structure on the line:

<blockquote>The construction of the Cardiff Railway has involved a number of heavy engineering works. There are nine skew bridges, five crossing the Merthyr river, three across the Glamorganshire Canal, and one across the River Taff. Near Nantgawr the River Taff has been diverted. The various cuttings and embankments are mostly of an extensive character. Ten retaining walls, 12 under bridges, 10 over bridges, a short tunnel and a viaduct contributed to the difficult nature of the work. The engineers were [[Charles Douglas Fox|Sir Douglas Fox]] and Mr. H. White, Mr. Herbert E. Allen, M.I.C.E., being resident engineer.<ref name = rlymag/></blockquote>
