In this month's edition of Narrow Gauge World we witness the launch of a brand-new steam locomotive but the final day of a narrow gauge railway – we are there as the Rhiw Valley Light Railway closes its doors after 50 years.

We profile the Lincolnshire Coast Light Railway and how potatoes combined with Pecketts

We gain an insight into long-lost railroads built to mine the mineral wealth of California

We celebrate 100 years of a German rack line

And we take a cab ride to an Indian seaside resort

In our modelling section we detail a whole range of exciting new releases in 7mm scale

And we look at three different interpretations of the Welshpool & Llanfair Light Railway.

All this, plus our unrivalled news coverage, the best photography and much more, in Narrow Gauge World 171.
