My 8 x 4 layout uses 90% Hornby track, including small radius turnouts and curved turnouts, plus a few pieces of flexi to fill the gaps and complete the layout.
I accept the shortcomings, I only use 2nd and 3rd radius curves, and accept the non-prototypical look. But, crucially, it all works, with a range of locos and stock, sometimes carefully chosen to fit with the shortcomings, it gives me pleasure and makes me HAPPY and that, to me, is what this hobby is all about.
