But I suspect - though I don't have a gradient profile - that it
flattens out before Euston.

Don't the underground tube stations generally have up-gradients
on the approach and down-gradients on exit to assist braking and
acceleration respectively?

AFIK, only the LU Central Line.

IIRC most of the Yerkes tubes have humps to some extent but not as
pronounced as the Central London Railway's

Most engineering trains I have seen were top and tailed by a loco, was
this train only out with one loco ?

But it wasn't an engineering 'train', at least in terms of loco and wagons.

It was a 'rail grinding vehicle' of some sort - and it was being rescued by
an out of service Northern line train.

It probably wasn't that kind of engineering train. (Which in any event
would be much harder to fail such a way that it needed a tow).
