Greetings everyone, I wasn't sure where to post this, but since it's a historical question, I figured this would be the right audience to aim it toward. After doing a little searching, I find little evidence that many domestic British steam locomotives were fitted with mechanical stokers. I see that some export locomotives were. What locomotives were fitted with them, and why didn't the technology really catch on? These devices had their advantages on larger locomotives and made the fireman's job easier. But I can also understand it adds cost and complexity to an otherwise proven method. Are the fireboxes on the larger British kettles relatively manageable with a scoop and some good manpower?
