I very much doubt that in those days they worked eight-hour shifts: the contractor got as many hours out of them as he could.
Yes I agree, as covered before on other threads, it's daylight hours and reasonable weather were the deciding factors on the whole.
Remember that they didn't have flood lighting in those days, so I am not convinced that they worked around the clock. Those working underground, such as in slate or coal mines, obviously worked in the dark with almost no illumination
Me neither. The town did have some gas street lighting at the time, but it was still in its infancy. In any case, the line was being constructed out of the town in fields, so it would have been very dark there at night.
This seems a likely explanation. Gangs = relays.
"Told off" could be in the sense of a bank teller, i.e. "counted off" or allocated into gangs of three. Rather than its current sense of reprimanded
I've since searched for the "told off" phrase for the era and it did indeed mean what you've just said.
Thanks for your input everyone, I can now imagine groups of three in relays working from the first cutting to the first embankment, a rough distance of around 1700 feet.
The Preston Herald newspaper also comes up trumps in early December 1870 and states that between 500 and 600 are now employed working on the construction of the line. These figures from December are more like it now, many of you have told me several times that there was probably hundreds working on it, and now it's confirmed.
Some time ago, I was looking at the 1871 census (not too long after the December article) and had the presence of mind to count up the numbers of people who had the skills to possibly be working on the construction, such as labourers, stone workers, carpenters etc. Given the December article's numbers (500 - 600), the 1871 census leaves me around 250 people short? could so many have been missed off the census?
