A hamburger restaurant has taken fast food to the next level by using miniature trains on a model railway track to deliver orders to tables.

Fritz's Railroad Restaurant in Kansas City has been in operation since 1954 when it was set up by the original owner and his wife Virginia Kropf following his return from the navy.

The fifties-style drive-in restaurant was a success from the off and Fritz added a second location in Kansas City in the mid-60s, according to the company website.

Ingenious: The train has been used for more than five decades and the innovation saved the restaurant from closure

It was around this time that the part-time inventor, who was struggling to get staff due to a shortage in labour, designed and developed a food delivery system, which he tested in his basement.

Before long the miniature railway system was installed within the restaurants and the novel idea was up and running, attracting more and more customers.

After retiring from the business, Fritz sold the restaurant on to his youngest son Fred and his wife, Mary, but continued to work part-time up until his death at the age of 83 in 2004.

The new owners were later approached by Crown Center Development and asked to open another restaurant in conjunction with the re-opening of Kansas City Union Station.

They installed a new train delivering service within the building, making sure they met the new government safety regulations in the process.

Today the restaurant is well known for its railroad theme and sells train memorabilia in the form of hats and toy engines for children.

The food is then lowered towards the customers where it can then be removed and placed on the table.
