Surprised no-one has mentioned this.
There are not enough 377/x sub-classes to number all the 387s as 377s AND keep sub-class demarcation unless 377/0 was taken up - and there is (or was) a good reason that I now forget why 377/0 is vacant.
375/0 375/1 375/2 were allegedly left vacant so the TOC could internally shorthand 4 digit numbers 50xx 51xx 52xx for 465s and 53xx upwards for 375s; I say allegedly as that theory falls down with 465/9 and 375/9, and for 6oxx with 466 and 376.
But there was something along that line within their TOC for 377s.
I was under the impression that there weren’t any 375/1s or /2s because the original combined electrostar order went from (375 or 377) /1 - /9 split between the South East and Southern. Of course the 377/5-7 wouldn’t have been planned initially. If extra electrostars had been ordered directly for Southeastern in the way they were for southern they probably would’ve ended using 375 /1 - /4
