Just for clarity, I should mention that I started down this road because I wanted to have a template that would extract information from the fields of each railroad and have words around that information instead of a table like I had previously. It just reads and looks better and also works much better on mobile (but I still have a long way to go there). The table the I used to have (as can be seen in How do you use Tiddlywiki in your research work? - #11 by HistoryBuff), I had an infobox with the information contained in the fields and the text field as the text to the left of the infobox. This new approach just seems more pleasant and easy to read. Besides, so far, most of the railroads don’t have anything in the text field and it looked silly with a blank tiddler and an infobox. This fills it all in for me that way. I can then use the text field to add details and further information that shows up in that History section.
Anyway, sorry for the ramble. I just wanted to give the backstory.
