From the outside it’s an unassuming bungalow perched atop a hillside.

But inside it’s every little boy’s dream.

It’s a veritable Aladdin’s cave, filled with railway paraphenalia including a model railway complete with East German locos and carriages in the garden.

But now Prof Paul Salveson, a very well-known figure in the Colne Valley, often known simply as ‘Mr Railways’, says he has decided to sell the home in which he has spent the past 18 years.

Sitting in the sunshine next to the ponds and railway track he says it will be a wrench to leave but he has decided eventually to go back to his native Lancashire.

Originally he arrived in Berry Brow in 1993 and worked at Leeds University in Adult Education.

He says: “I’ve loved railways since I was a little kid hanging around Bolton engine shed. It was steam power that drew me in and I’ve been hooked ever since.

“I began collecting in my 20s and I’ve amassed quite a large collection of railway books, timetables and other items ever since.

“I’ve spent nearly 40 years in the railway industry and have been there at the sharp end too.”

Railway expert Dr Paul Salveson 'Mr Railways' selling his Slaithwaite residence, garden railway not included.

In recent years a highlight was Paul’s annual garden party when guests were able to enjoy a visit to his home in Radcliffe Road, Slaithwaite, which overlooks the railway which runs through the Colne Valley.

The railway which greeted them was a Gauge One garden railway with equipment from LGB, a respected German company complete with a lot of old carriages and locos from East Germany.

Paul, a grandfather, added: “I know the East German railways quite well.

“I have very mixed feelings about going. I like Huddersfield and I like the people who live here.

“It’s a very good railway town. But, of course, I will keep up my connections with friends.

“There are a lot of good things happening in Huddersfield railway-wise.”

Although he is best-known for his interest and expertise in railways he has also been active politically and has been a key figure in left wing politics for years.

He spent several years as a Kirklees councillor.

And as well as a passion for steam and railways he has an almost equally absorbing interest in dialect – his PhD was in Lancashire dialect.

As for the house sale he says: “I put it on the market last week and it’s very early days. I have had a couple of people interested.”

The property is being marketed by Simon Blyth. And the garden railway layout is available by separate negotiation.
