Does anybody have any thoughts or info on Summer 1957?

The 1957 Railway Observers say very little, apart from noting the transfer of 60003, 60008, 60010 and 60030 to Grantham, in exchange for 60044, 60103, 60136 and 60139.
It does mention that the first observed working of 60010 from Grantham was on the 0550 ex-Kings Cross on 4th April.
The corresponding Railway Magazines for 1957 say very little also, except to repeat the numbers of the transferred locos, but the June 1957 Trains Illustrated (well, it is a miserable day and SWMBO is away until this evening
) comes up with this:-
"We understand the reason for the change is that the A4s now prove heavier on maintenance even than the A3s, let alone the A1s; in particular, an unexplained tendency of A4s right hand driving axleboxes to overheat is causing concern. Following the transfers, a series of dynamometer car trials was concluded between London and Newcastle with A3s to test their ability to tackle through workings between the two cities."
However, back on the local services The Railway Observer blows my theory out of the water by saying (I have altered printed times to 24 hour clock):-
"On and from 10th March, the Sunday Grantham-Nottingham-Derby service has been improved. An additional train formed of a diesel unit now departs Grantham at 1420 for Derby Friargate, returning at 1545. The 0740 and 1830 Granthan - Nottingham Vic. forming the 0905 and 2015 return workings are now diesel operated. The 1110 Grantham - Nottingham Vic. is also a diesel working and is extended to Derby and forms the 1230 return."
Also from the June issue:-
"The new two-car Derby built steel sets in the Lincolnshire area are not adequately powered to enable them to operate the existing schedules with the addition of a van or horsebox, as was the case with the lightweight units. Accordingly, certain services such as Skegness - Grantham and Lincoln - Boston are running as three coach sets with the addition of an extra power car. Even so, the 1 in 122 bank west of Ancaster reduces one of these sets to 45 m.p.h. Examples noted in traffic are 50008/50007/56007, 50011/50012/56012, 50038/50039/56015 and 50015/50035/56035.
The spare trailers are stored in various places, 56016/25/40 at Blankney & Metheringham, 56010/39 at Bardney and 56004/20/22/37/38/44/45 near Sleaford South Junction."
