The best way to show the inner workings of a steam engine?

35029 Ellerman Lines - Merchant Navy class (sectioned) - How a Steam Engine WorksThe fate of this locomotive has always been a controversial one.  Merchant Navy class 35029 Ellerman Lines was once one of the pride’s of the Southern Region’s steam locomotive fleet.  Although it avoided death in a  scrapyard, this locomotive did not survive another cutters torch completely and will never be steamed again.  It now serves as arguably the biggest 3D diagram of how a steam locomotive works.  The controversy of course comes from the fact that this piece of UK Heritage is now doing the job a diagram could do.2013 National Railway Museum York - The Great Gathering - BR Merchant Navy 35029 Ellerman LinesHowever, the controversy is not one of the biggest in steam preservation.  35029 is one of 11 surviving members of class of 30 locomotives that are so big that they are not economic for use on many preserved lines.  As such, this does give things a different perspective.  As 3D diagrams go, it is rather good too!  It is a great way to show how a steam locomotive works.  One of the best sources I’ve come across on this subject is from a fellow wordpress website (click here to read it).  If you compare the two pictures above with this piece you will get an impression of how good the sectioned 35029 Ellerman Lines is.
