As we’ve seen from the tragic accident in Scotland last week, the U.K. rail network is facing an existential risk from the climate disaster. That might sound hyperbolic. But when you consider the likely future of self driving cars, a dramatic reduction in vehicles on the road as a result; the rise of electric bikes and the inevitable mass rollout of associated infrastructure, it doesn’t look promising for the rail industry.
As I’ve recently written, the rail network is already going to be threatened by the other forms of transport I’ve mentioned due to the fact that the network hasn’t been invested in for so long. It’s not like in Japan where they wouldn’t walk away from such a great system. Loyal daily passengers will only remain loyal for so long if they’re dissatisfied with the service they’re receiving.
But it’s when you couple that with the threat of climate change that things really unravel. I’ve been following the weekly update videos Network Rail put out on their YouTube channel for a while now. There’s an obvious trend in that they’re constantly having to fix damage caused by extreme weather. It’s mainly landslips but also work on reinforcing sea walls to protect against sea spray. Landslips in particular must be costing NR huge amounts of money, and it’s money that is not being spent on upgrading the ageing infrastructure. Watching TV shows about railways just shows how much disruption is already being caused from rain, storms, heat etc. It’s only going to get worse, and as we’ve seen this week, it can be deadly.
Road transport I believe to be at less risk from the climate disaster, but I would say the main benefits will be as we switch to autonomous driving. Because we have so many privately owned cars, the cars are parked all over the country, so whenever extreme weather hits, the cars can’t be moved and they get written off and float down the road.
However, once we stop owning cars and we replace them with self driving fleets, the number of cars in the country will drop potentially 90%. This will not only eliminate traffic, but it will also allow vehicles to avoid flooded roads or be moved to a safe location before the weather hits if it’s scheduled to hit a wide area. Because our road network is completely connected, if one road is flooded, they can go another direction. Trains can’t do that, and that’s a giant problem that the rail industry will struggle to get around.
Since the benefits for road traffic mainly take effect once we go autonomous, and that technology doesn’t exist yet; at the moment the only way to minimise the risk of flood or storm damage is to get rid of your car and buy a bike. Even a big, heavy cargo bike can be taken upstairs with your couch and the rest of your belongings. You’re not going to leave it to be flood damaged if you can avoid it. With a car, there’s very little you can do, especially if the weather is unexpected or worse than forecast.
It’s true for the infrastructure as well. It would be far cheaper to build elevated bike routes and bridges in high risk areas than it would be for other modes. We need to do everything we can to improve infrastructure and reduce risk. Invest in the rail network, move away from car ownership, and make us a bike society.
