They certainly look better than the old ones with a lot more features.
I was surprised to see a bin in the carriage because I thought they banned them from all station platforms, so why have them on the trains?
There will also need to be a few upgrades to the platforms.
'Platform & power upgrades
Vital upgrades are being carried out on around 100 Merseyrail platforms to help make sure the network is ready for the new state-of-the-art trains and their sliding step technology.
This technology will make it much easier for people, including wheelchair users and those with prams and luggage to get on and off the trains.
In order to improve journey times, additional power infrastructure is also required. This includes new connections to Scottish Power’s network and additional substations, doubling the system’s power.
The enhanced system will enable regenerative braking which will reduce energy consumption and the railway’s carbon footprint.'
What these upgrades involve and how long they take is anyones guess.
If the coronavirus pandemic didn't happen, I suspect we would have had these new trains and upgrades in place by now.
