Hi everyone. I'm the author of that blog post mentioned above (thanks for visiting) and I'm looking for the Excel file created by SirJB7. I'm interested in seeing what's possible when trying to create train schedules like this in Excel. Does anyone have the file?
I edited my previous comment with a new working and permanent link to the related file.
Within the workbook you'll find a sample schedule file from a local railway branch that passes near my home. The data source is originally a PDF file which has been copied and pasted. If you have another input source or design just get back to me and we'll see.
