And I thought of the humble metro trainset

50-odd tonnes and I've witnessed zero to 80km/h in about 6 to 10 seconds or so.

But, yes a nice big yellow machine running on batteries is an impressive milestone.

1.3 m/s² is quite something, quite a bit more than a typical tram or S-Bahn (both ~1 m/s², which is still quite a pull...).

The drivers only do the high acceleration when the tram is mostly empty and no standing passengers I've noticed.

For those in Birmingham UK: St Paul's to Jewellery Quarter is a longish bit of track just outside the city centre.
