The 'nose' also serves as the boat-tail when running 'backwards'.
Japanese Railways had been experimenting with 50+ foot 'nose' extensions to help mitigate dramatic pressure spikes experienced when the trains entered or left tunnels.
I think the 'odd' noses are part of the stable of research items tested.
If anyone has had to do an emergency landing from high altitude with failing cabin pressure you're aware of the inner ear pain which one can experience for days afterwards.
I applaud their efforts to help with passenger comfort.
