Does anyone know why they have not taken it through Canonbury tunnel to
Finsbury Park? Lack of money or lack of understanding of London's
public transport requirement? It looks at though some work is being
done to facilitate trains through the tunnel again.

I wasn't aware it closed... it was singled when the overhead went in,
because there isn't room for double track with overhead.

Specifically, i think it's that there isn't room for a double track
bearing freight trains with overhead. Freight trains being taller than
passenger trains (passenger trains all fit in W6A in this country, i
believe; squinting at a map from 2004, it looks like the Canonbury curve
might be W9).
