Since the first primitive iron horse, rail has broken records and these days it's no different. We look at some contemporary examples of amazing railway engineering.
From the tallest to the deepest, to the oldest, the world of railway engineering is full of extremes. We look at the contemporary bridges, viaducts and tunnels which are pushing the limits of today's railway engineering.
The tallest railway viaduct
Taking four years to complete, the Mala Rijeka Viaduct or 'Little River viaduct' on the Belgrade - Bar railway, rises 200m above the river valley below. The impressive structure contains 36,000m³ of concrete and 100,000kg of steel. To put that in perspective, the concrete base for the largest supporting pillar is the size of a tennis court. It's not to be confused with the tallest railway bridge, an accolade that goes to China's Beipanjiang River Railway Bridge.
The steepest funicular railway
If you consider descending off a 200m cliff scenic, then Katoomba Scenic Railway in Australia's Blue Mountains will live up to its name. With a 52-degree incline this is the steepest cable railway in the world, so overcome your vertigo and take the 310m plunge. You'll be treated to miles of Jurassic rainforest when you reach your valley destination.
Europe's highest railway station
Although the world record for highest railway goes to the Qinghai-Tibet railway in Asia (at over 5000m above sea level) we thought we'd put the spotlight on Europe. At over 3000m, the Jungfraujoch railway station, in Switzerland's Bernese Alps, is Europe's highest, thus deserving its nickname as the station at the 'Top of Europe'. It can be reached via a 7.3km long railway tunnel, accessible from nearby Interlaken. If you've got a real head for heights make your way to the observation deck for spectacular Alpine views.
Europe's longest rail and road bridge
The Oresund Bridge stretches from Copenhagen in Denmark to Malmö in Sweden, allowing cars and trains to cross the 16km stretch of water which separates one country from the other. If the image below looks like an optical illusion it's because the 2-track railway and 4-lane highway abruptly descend into the sea as the bridge becomes a tunnel for the last stretch. Is it a tunnel or a bridge? Either way it's bar far Europe's longest road and rail bridge.

Longest undersea tunnel
The notion of a tunnel under the Channel was first envisaged back in the 1800s. Nearly 200 years later, and after three years of digging, there was literally light at the end of the tunnel, as the machines boring through the seabed finished their task. The tunnel takes car trains and passenger trains and actually consists of more than one tunnel. Affectionately known as the 'Chunnel', the Channel Tunnel now boasts the world's longest undersea tunnel at 35km.
The world's first undersea rail tunnel
From the world's longest undersea tunnel to the world's first. Though not initially designed for rail traffic, London's Thames Tunnel was the first of its kind. Designed by the Marc Isambard Brunel it was considered the '8th Wonder of the World'. And after 18 years under construction half of London's population paid the penny toll to walk the tunnel when it finally opened in 1843. Since 2010, it's formed part of the new London Overground service that connects Rotherhithe with Wapping.
The deepest railway tunnel
Japan's Seikan tunnel connects the islands of Hokkaido and Honshu via the notoriously stormy Tsugaru strait. Despite being in a known earthquake zone, dynamite and drills were used to blast the tunnel through rock down to 790 ft below sea level. Despite this danger it was a much-needed alternative to boats, which frequently sank in the treacherous waters above. When it was opened it was the longest and deepest railway tunnel in the world, but is now eclipsed by the Gotthard Base Tunnel (below) in the length stakes.
The longest railway tunnel
The 57km Gotthard Base Tunnel in Switzerland is the world's longest rail tunnel. Costing €11bn to construct and 17 years to complete, the tunnel cuts 45 mins off the journey time between Zurich and Lugano to just under 2 hrs and enables rail freight transportation via the Rhine-Alp corridor.
Oldest railway tunnel in the world
In Derbyshire, England, archaeologists have unearthed a tunnel dating back to 1793 which they believe to be the world's oldest railway tunnel. Train experts may point out that the advent of the steam engine wasn't until the early 1800s and they'd be right. However, it's thought the tunnel was the conduit for horse-drawn trains before being used by steam locomotives during the 20th century.
The amphibious train
We've blogged on train-boats and boat-trains before, but we couldn't resist another mention for amphibious trains. The Ostróda-Elbląg canal in Poland is a beautiful example of where rail and hydro engineering combine. To move from one canal to another at a higher level, boats on the Ostróda-Elbląg go a short distance by rail, solving the problem of a difference in canal elevation.
