Then another four-wheeled car was built, drawn by three horses, so as to carry six passengers on each side.

And lastly, a fourth horse was used, and the car was further enlarged, so as to accommodate seven, and eventually eight passengers on each side, with one on the box, which made a total accommodation for seventeen passengers.

The largest and heaviest of the long cars, on four wheels, was called "Finn MacCoul's," after Ossian's Giant; the fast cars, of a light build, on two wheels, were called "Faugh-a-ballagh," or "clear the way"; while the intermediate cars were named "Massey Dawsons," after a popular Tory squire.
When Bianconi's system was complete, he had about a hundred vehicles at work; a hundred and forty stations for changing horses, where from one to eight grooms were employed; about a hundred drivers, thirteen hundred horses, performing an average distance of three thousand eight hundred miles daily; passing through twenty-three counties, and visiting no fewer than a hundred and twenty of the principal towns and cities in the south and west and midland counties of Ireland.
Bianconi's horses consumed on an average from three to four thousand tons of hay yearly, and from thirty to forty thousand barrels of oats, all of which were purchased in the respective localities in which they were grown.
Bianconi's cars--or "The Bians"-- soon became very popular.

Everybody was under obligations to them.

They greatly promoted the improvement of the country.
