We bought our house over 30 years ago mainly because it had huge loft obviously a railway room but only advice I would share would be have it converted properly so you don't have the heat in summer and cold in winter.
Nice quiet me space.
My experience of both Snow Hill and New Street in the 60s was Snow Hill was very much lighter only smoke as said before, came from tunnel mouth. This is fascinating modelling really capturing how I remember Snow Hill, lucky chap to have this built to such a high standard.
Born in Bewdley I heard, but don't remember, stories of excursions to South Wales that used theTenbury branch to Wooferton, I would have thought these needed banking through the Wyre Forest.
The track bed has quite an incline on it any ideas?
Fabulous project used Snow Hill regularly on spotting trips from Bewdley in late 50s early 60s lovely station, can't wait to see this develop excellent work really like it.
