This is a Wallis & Stevens overtype steam wagon, built at their works in Basingstoke, Hampshire. There is to my knowledge only one surviving example, and that is owned by the Hampshire County Council Museums Service, and it might be on display at their "Milestones" museum in Basingstoke.
There they have stuff from Hampshire manufacturers like Taskers, Wallises and Thorneycroft. Buggyite (forum member)
This is Pickfords transporting part of the Electric Shovel to B.L.I. at Tunstead, finding themselves in a spot of bother under the Viaduct in Buxton, Dukes Drive I think. Shallcross (forum member)
It's definitely a Scammell tractor unit, and very probably the low-loader trailer would have been made by them, too. As can be seen, the wheels are shod with solid rubber. Its quite hard to say when it would have been built, but I think they only started making articulated wagons in 1921, and from other photos out there, I suspect that the customer had the choice of solid rubber or pneumatic tyres, probably up till around 1930.
The big steel discs that can be seen lying around the road were used on soft ground under the wheels to spread the load, and prevent sinking. Something they should have been using beforehand, I'd suggest! Next time I go along Dukes Drive, I will have a look if there is an outlet from a spring opposite where this happened, because it very much looks like they've broken into a culvert.
Dukes Drive has a weight limit on it these days! Any theoretical time saved in using Dukes Drive instead of Dale Road will certainly have been lost many times over in jacking and packing the load up, then the trailer, then finally the back of the tractor unit. Buggyite (forum member)
This photograph was from a pre 1920 postcard. The poster required information about it and asked was it the Rocket. Below is the reply.
It's not The Rocket, as that locomotive had only one pair of driving wheels, as per the photograph of the original. There have been various replicas made over the years, with the cylinders more steeply inclined, and with a chimney design, but they all have the 0-2-2 wheel arrangement. Your photo is of an 0-4-0 loco, and is similar to Sans Pareil, one of the other engines that took part in the Rainhill Trials. The trouble is, Sans Pareil had cylinders mounted vertically, so it's unlikely to be that one.
After a bit of research, I reckon it is "Invicta", built by George Stephenson for the Canterbury & Whitstable Railway in 1830.
It stood on a plinth outside the city wall in Canterbury for years, but has subsequently been restored yet again, and is now in Canterbury museum.
