It's a Bachmann model of a Great Western 0-6-0 goods engine designed by Collett in the 1940s. I described it as a toybox wreck because, although it is quite an accurate model, it had clearly been knocked about as it would if it was thrown in a toybox after use. The model probably dates from between 2008 and 2010, so it's not very old. I knew the real engines when I lived in Somerset as a teenager. The branch line between Highbridge and Evercreech Junction used them in the early 1960s. Many lines were closing and local freight traffic was reducing, so many of these engines were being scrapped. If they were in working condition, they would be sent to a line like ours, and be used until they needed maintenance, when they would be sent for scrapping and be replaced by another. Hence the lack of cleaning, reflected in my model!
