LNER / BR Thompson B1 "Antelope" 4-6-0

The London and North Eastern Railway Thompson Class B1 is a class of steam locomotive designed by Edward Thompson for medium mixed traffic work. These 4-6-0's were designed to replace the aging fleet of non-standard locomotives from many pre grouping regions, mostly the aging 4-4-0's, the D49's, and more. Through standardization, the class become over 410 strong, making them the second most mass produced 4-6-0 of any class on the british isles.

The B1's were very fast too for their work, reaching speeds up to 90 MPH on some areas of the networks, and having such a light axle loading, meant they could go to many other places some other engines couldn't.

That being said, it made them rather light on their feet, and their massive fireboxes meant that mainline crews who were well known for strength were optimal for driving these machines.

While only 2 survive in preservation, their impacts on BR were not gone un-noticed, with the last ones being withdrawn in 1967.


Since the grand total was about 410, I will allow as a maximum 2, but if a good enough reason is provided, a third can be claimed (DO NOT ABUSE THIS)
