By 1833, Dinas Powys barely existed, but was still larger than nearby Penarth, until Penarth amalgamated with Cogan and Llandough to form a new Town Board.
However, St. Andrews Major was at the time substantially larger than Dinas Powis, but even added together their population was still only 474 in total.

The village population had remained almost static at about 300-400 people until the second half of the 19th century when there was an influx into this thriving rural community, including a large contingent from the West Country.
The growth of the coal industry saw the first passenger train arrive in Dinas Powys on Sunday, 20 December 1898, and thereafter the population increased rapidly.
The new rail link was laid at the bottom end of the Dinas Powys valley and provided a rapid link to the new docks that had been built in Cardiff, Barry and Penarth to handle the expanding coal trade from the South Wales valleys.
At that time the only features below St Andrews Major were the small hamlet of Dinas Powis, the rail line, Cadoxton Brook and a number of small farms.

The new rail link provided far better communication and transport to the area making it a more attractive residential prospect and many workers from Barry and Cardiff moved into the Dinas Powys area.
As quickly as 1891, the village population had already more than doubled to 1,149 and by the turn of the century ten years later, had expanded to over 2,000.
The village expanded in two ways as from the railway link towards St. Andrew's Major many imposing and fine houses were built, in contrast to the 'railway suburbs' that grew up along the railway, near the current area of Eastbrook, where the new housing was of more modest proportions.

Just a few years after the railway was constructed, the main Cardiff Road was developed over the previous unmetalled trackway that followed the route of the railway line.
This provided a further burst of population growth and house building.
