Model train maker Hornby reported a surge in profits over the last year as mature collectors continued to buy up its ranges.

The group, which makes Hornby model railways and Scalextric car racing models, said pre-tax profits for the year to March 31 jumped 62 per cent to £3.7 million while turnover leapt 16 per cent to £28.5 million.

Chief executive Frank Martin said: "There is a genuine resurgence in interest in our hobby ranges among adult collectors and enthusiasts.

"The demographic pattern of the post-war baby boomers entering their 40s and 50s with more time and disposable income than ever before gives real confidence that the current favourable market conditions will be sustainable for the foreseeable future."

Still among the best sellers for the group is the ever popular Thomas the Tank Engine, but the real success last year was the Harry Potter Hogwarts Express train set.

Mr Martin said the group sold about 10,000 sets during the year.
