The other factor is the angle, as with wheelchairs and pedestrian rail crossings unfortunately.
If you hit the edge of the rail on an angle at a slower speed, your wheel gets flipped sideways then drops into the gap. Kiwirail have done nothing to address that on the Morningside and other crossings, and their report into the horrific incident there somehow omitted it.
I think you want to take the opportunity to be best-practice, and "fast/slow bike lanes" ain't it (who exactly is "fast" or "slow"?). But separation by direction and from pedestrians is. A couple of exhibits below from my recent trip through the Netherlands; basically treat the cycleway like a road (with a centreline for keeping left and overtaking in the opposing lane) and a stepped-up pedestrian area on either side. Throw in a few user symbols and direction arrows to help explain things to NZers. Ultimately though, the amount of width available here (compared to our usual anaemic shared paths) will be the biggest thing producing a good result - don't be coloured by your bad experiences on sub-standard paths elsewhere.

Thanks Glen. I had been wondering about this.

Maybe better to just call them overtaking lanes. When someone want to overtake, it's pretty clear who is fast-er and who is slow-er.
But yeah, I can't say I've found overtaking to be much of a problem on any cycleway except the one on Tamaki Drive, where even just riding slowly can be quite difficult, and riding fast is simply not possible for long stretches.
The proximity to the CBD might make the pedestrian aspect of this development bigger than other cycleways we have, at times. But if they have their own generous space, it's a quantum leap up from any cycleways I can think of in Auckland.
