That railways should be nationally owned and operated

I'll just make one brief statement for the opposition.

Private companies have the ability to invest in multiple long term strategies which politicians don't due to term times and election cycles. This means that private companies and not politicians have the ability to enter into long term projects that will improve the standard of the whole service. Private companies still have the incentives to run an efficient and useful service because they still depend on good customer feedback otherwise another company can bid to take over the service. The company is beholden to shareholders who need the company to continue to thrive for a long time if they want to see continuous returns and rewards. This means that a private company would have the incentives to run a successful service that will last by constantly updating it and improving it. A politician wants to spend as little money as possible and if it isn't about to completely collapse before the end of the term that's fine to them. This leaves them little incentives to constantly spend money to upgrade the service provided.
