Their mechanical stokers also proved to be troublesome and were eventually removed.

These discharged onto mechanical stokers and into the boiler furnace.

These later locomotives had mechanical stokers and bogie tenders.

Mechanical stokers for feeding coal to locomotives were in use in the 1920s.

Babcock and Wilcox supplied 24 boilers fitted with mechanical stokers.

This class also featured a superheater and many have mechanical stokers to feed coal into the firebox.

Sixty-nine L2 locomotives received mechanical stokers and were reclassified as class L2-r.

They were equipped with mechanical stokers and Vanderbilt tenders and weighed 185 tonnes in working order.

QJs were equipped with mechanical stokers, feedwater heaters, electric lights, and air horns.

They were superheated and had Walschaerts valve gear, bar frames and mechanical stokers.

The locomotives in the final order from NBL, number 3057 and later, were delivered new complete with mechanical stokers.

Fireboxes became so big that firing a steam locomotive became an extremely difficult job without the aid of mechanical stokers.

This class had the largest boiler and firebox of any Turkish locomotive and were the only one fitted with mechanical stokers.

The 20th class was the first and only class of Rhodesia Railways locomotives to be fitted with mechanical stokers.

As in 356, augers were used to feed turf from the bunkers to the firebox, where two mechanical stokers were fitted.

In later years, when the Class 15F was being relegated to heavy shunting and local work, many of the post-war locomotives had their mechanical stokers removed.

Steam for the first two pumping sets was supplied by three Lancashire boilers, which were fitted with mechanical stokers, operated by hydraulic power.

The boilers were fed by mechanical stokers using coal known as Shaw slack with a calorific value of 12,963 Btu/lb.

The locomotives were not equipped with mechanical stokers which made the job of the fireman harder as he had to throw the coal uniformly throughout the firebox.

Finally, there were changes associated with the difference in fuel; the coal-fired Leader did not require the augers, mechanical stokers and induced-draught fans fitted to CC1.

In the United States, various steam-powered mechanical stokers became standard equipment and were adopted and used elsewhere including Australia and South Africa.

It was soon evident that mechanical stokers could function perfectly across the connection between a Garratt's boiler and engine unit, making the rationale for the Union-Garratt obsolete.

Some of the examples that survived the longest were those fitted with mechanical stokers and Kylpor blast pipes or Giesl ejectors to improve their performance and reduce smoke.

The early post-war locomotives built by BP and NBL in 1944 and 1945, like the pre-war NBL-builts, were built without mechanical stokers, although provision was made for their subsequent conversion to mechanical stoking.

The pre-war Class 15Fs were hand stoked and were delivered without smoke deflectors, while the post-war locomotives were built with mechanical stokers, smoke deflectors and vacuum brakes on the driving wheels as well as the tenders.
