Plarail/Pre-2009 TrackMaster Axels

Well this is what I ordered and if they turn out to be too long I will just cut them.

0.7mm diameter is an interesting choice. I wonder what diameter the flat heads are.  No doubt you'll update us when they arrive.

Meanwhile, these look good, available in 3mm (M3) diameter and 35mm or 40mm long:

And these would be brilliant but the longest I've found so far are 30mm which probably isn't quite enough:
