So ... according to the FIM, Hellstrom-Bangs ban applies to Sweden: https://fimspeedway.com/news/hellstrom-bangs-swedish-league-ban-halved  

Not sure what if any impact on Workington but development of Land at Oldside (land adjacent to the stadium ?)

All those who are worried about the track surface may want to know some of the history. Spedeworth changed it from tarmac to shale to ensure the Dutch F1 drivers continued to support major events at the track. The shale was laid on top of the tarmac (I don't know how deep it is) and Spedeworth have worked hard to make it a good surface which does not rut up with the F1's on full power. I am sure they have the equipment to make the track suitable for Speedway a few days after a Stock Car meeting as Deane Wood, the boss of Spedeworth, would not want to have his stadium criticised for a poor track surface. He was a very accomplished Stock Car driver and understands how the track surface is critical in making for good racing.

I would imagine most stadium leases would be a full repairing and insuring lease.   If the damage was done over 2 nights, it's a shame no one knew after the first night.

Obviously, there have been problems to overcome, and it's taken longer than hoped for to bring Northampton online. But yesterday we got the news that Northampton are running. Today we got their fixture list. And in the coming days we'll know the promoter, team manager and the riders. We have positive news coming out, and still people are moaning?    Unbelievable.
