| 1. | Their cylinders were reamed from bore and the boiler pressure reduced from.
|
| 2. | Mechanics managed to burn wheat flour to maintain minimum boiler pressure.
|
| 3. | From 1886 onwards, only the variant with the higher boiler pressure was built.
|
| 4. | Another modification was the reduction of boiler pressure to to reduce maintenance costs.
|
| 5. | Necessary safety valves are located at suitable points to relieve excessive boiler pressure.
|
| 6. | Alfred Holt had experimented with a boiler pressure of 60 psi in seagoing vessels.
|
| 7. | A facility for checking boiler pressure performance is located here.
|
| 8. | Tractive effort was calculated at 15, 330lbs with a working boiler pressure of 200psi.
|
| 9. | Their tractive effort was 14, 650 lb at 75 % of working boiler pressure.
|
| 10. | The boiler pressure setting of rebalanced locomotives was reduced from.
