In response to requests about how the ‘new new Bristol’ compares with the ‘new Bristol’ and the ‘old Bristol’, here’s a comparison. For more on the changes, see my earlier post. The light blue triangle shows the constant 36-degree banking of the ‘old Bristol’. The black line shows the progressive banking (24-30 degrees) that was introduced in 2007 and the red line shows how (I think) they are modifying the highest groove only. Note that there seems to be some disagreement about the actual banking values. I’m using the values the track uses.
