Unfortunately, there are many possibilities. The TR cooling system is also
kind of marginal in stop-and-go traffic, so what you are seeing may be
normal.
One thing that may help is to run less anti-freeze. Using 2:1
water/antifreeze will still provide freeze protection down to 0F (-18C), but
better heat transfer than the recommended 50/50.
Make sure your cardboard shroud (between grill and radiator) is in place.
Check your grille against the dimensions here:

Redline "Water wetter" may also help.
What many folks have done is modify the car to create more airflow when not
moving (or moving slowly). Using a plastic fan with more pitch from a later
Triumph is popular; or what I did was to remove the mechanical fan and
install an electric fan in its place. (I made a few other mods, but IMO the
fan was the magic bullet.)
