We must use this line at different times as 150's are used more than you think.
I guess we must...
I usually catch either 2C11 or 2C15, occasionally later, from Harrogate to Leeds, so get to see a snapshot of the weekday AM peak from around 0745 to 0845. In the evening my departures are far more mixed across the PM peak, from 1700 through to 1830, occasionally later.
As it happens, the fact that 170's had legroom led me to want to figure out what services were served by them ... so I could target my commute better. I started to keep a tally of just what unit compositions I saw during my commute, both for the trains I caught and for the services running in the opposite direction. From that I built up my own idea of the diagrams in use, and the units that were allocated.
Then I decided I would keep it going over the summer, to see what volume of failures/swaps we saw, in preparation for the (as-then) expected higher volume services, and the arrival of more 170s.
What it means now is that I have a tally of all the observations I've made over the last 5 months. It really doesn't show that many sprinters, and certainly not that many 4-car sprinters. And the one diagram where you are most likely to see them is 2C11, one of my regulars.

Key:
P = Pacer
S = Sprinter 150/153/155/156
X = 158
M = Mixed Pacer + Sprinter
T = Turbostar
U = Unknown
C = Cancelled (likely only 1 service of the diagram)
