1 - Built by Kinmond Brothers of Montreal, Works No. 9. Damaged beyond repair when the Carillon engine house burned in 1895. Scrapped a few years later.
2 – Built of Daniel C. Gunn of Hamilton, Ontario, Works No. 25. Leading wheels attached directly to the main frame so the wheels did not swivel. Scrapped in 1914.
3 – Inspection engine with an upright boiler and not much bigger than a hand car. Acquired 1867. Scrapped about 1880.
4 - Built by Peto & Co. Canada Works, Birkenhead, England as a 2-2-2 for the Grand Trunk bearing either Works No. 29 or 34. (British historians have reconstructed two differing versions of the Canada Works Builder's list.) It was possibly numbered 70 on the Grand Trunk. Rebuilt to a 4-2-2 by the Grand Trunk in 1856 and then to a 4-4-0. Acquired by C&G 1874. Renamed Ottawa after the Kinmond Ottawa was retired. Scrapped in 1914.
Carmichael & Brown of Montreal built one first-class coach and one second-class coach for the railway. O'Meara, another Montreal builder, produced at least one second class coach.
In the 1858 Samuel Keefer report is a summary of rolling stock signed by Carillon & Grenville Superintendent J.F. Bernard:
| Description | Number of cars |
| First Class Passenger 8 wheel | 2 |
| Second Class Passenger 8 wheel | 4 |
| Baggage Mail & Express 8 wheel | 2 |
| Platform car 8 wheels | 4 |
| Hand car | 1 |
Shortly after this report was issued, one passenger car and one flat car were converted into baggage cars.
At least two of the second class passenger cars were subsequently converted to combination baggage-coach configuration. The car body of Carillon & Grenville's O'Meara built coach survives at the National Museum of Science and Technology (NMST) in Ottawa as a combine. There is also photographic evidence of another combine with an arch roof.
