What counts as a microfleet?

[35B]

Goldfish62 has brought up something I'm forever moaning at people about -- calling fleet microfleets when they're not.

I think "microfleet" has to be one of the most wrongly overused terms on this forum. In threads discussing future Southeastern fleets, Class 376 and 458/4 get described as microfleets often, for example, despite being 36 and 28 strong fleets! Working alongside a very large fleet (465s) does not make them a microfleet.

I disagree. I think the term is well used in circumstances like the 376 or 458/4 where provision of that fleet means that the trains involved require separate management for use on a common set of services, imposing additional parts and training obligations on the operator.

In these cases, it is not the absolute size of the fleet that counts, but the impact on operational management.

My comment is a lot of whataboutery but interested to hear your thoughts.

Would you take into account the wider scale of the fleet as well? If my imaginary TOC had 200 units of 387s but also ran 20 units of 319s, would the 319s count as a microfleet if compared to the rest of what I run?

Or say, for example, I have many of the same type of train but different classes, for example a bunch of Desiros split into fleets of 9 350s, 9 360s, 9 444s, 9 450s, but also a random fleet of 9 150s, are they all microfleets or would you lump the Desiros together and count the 150s as a microfleet?

LNER's 897s under construction must come under a microfleet, as they are only 10 of them and are very different to all the IETs they use. There may also be a similar argument for the 745s, which also have two different interior layouts and are supposed to be put on different dedicated routes (though often end up interchanging).

By my original definition the 897s are a microfleet in terms of numbers (just 10 trainsets) and how the role could've theoretically gone to more bi-mode Hitachi units with cost of procurement being the only factor, but they do still have some flexibility in terms of where they can be used on the LNER network. The 745 I would argue is a bit different because it's filling a unique role as an intercity unit on the Great Eastern route which couldn't have gone to a 720, but at the same time it's not exactly the same as the other express passenger units on the network.

Is Waterloo & City line rolling stock a microfleet? As far as I know, length is the only difference with the remaining stock on the Central line, which definitely isn't a microfleet.

I thought the two fleets had diverged on some technical respects over the years, and are now not compatible.

Should we also consider the national fleet rather than just the fleet within a particular TOC or operating area of GBR?

So while the 150s used on the Marston Vale line are a microfleet in terms of WMR, there are still hundreds of them running around other parts of the country

A bit of an exaggeration. Two 150/0s, fifty 150/1s and 85 150/2s for a total of 137.

The original 150/0s, with their unique non-driving centre cars, are without doubt a microfleet.

So would the ten original "Peaks", AKA class 44, be considered a microfleet?

Having been ostensibly constructed as prototype units, 001 and 002 also feature other technical nuances, as a result of various modifications throughout their working life.
