Graham,
Do the local and national press accurately record the detail of current events?. The answer is they often have bloopers. Do you think the hacs back then were any better?. These old engravings are best taken with more than a pinch of salt

Comments on Wikipedia/Wikimedia regarding the picture of the steam circus suggest it is a 20th century artists impression rather than a contemporary illustration.

There is very little historical information to go on, but it seems likely that the original went chimney first. The replica, on the other hand, is an 0-2-2. This was done to allow it to be fired on the move, and to avoid the crew being in close proximity to the motion.

You're right, there does seem to be very little historical information to go on. As far as I can tell, that "Mechanical power subduing animal speed" illustration is the only one drawn from life, rather than later copies or speculation.
Even the Catch Me Who Can web site has almost no information about the original, what happened to it or where they got plans and dimensions etc. from.
Looking at some of the other vehicles on https://en.wikipedia.org/wiki/Richard_Trevithick , lack of comfort and safety for the crew seems to be a common factor, so I suppose the builders of the replica have had to compromise between historical accuracy and modern safety standards.

Most of the design is taken from the surviving Hazledine-built stationary engine in the Science Museum. The engraving on the entry ticket provides the best clue as to the relative size of the wheels. There are surviving documents and drawings of other engines that when assembled allow quite a lot to be deduced.

Probably the best book on Trevithick is Dickinson & Titley. Francis Trevithick's work is interesting, but it is unreliable. Anthony Burton's book is a good read, but not as technically detailed.

As to compromises, you are right. For example, the replica boiler is not an iron casting!
