Locoyard Review



Exquisite! Push-pull equipment correctly only one long-frame versions (see above.)  Fantastic cab (see below) with cab windows open!



Captured perfectly, having seen the M7 in the flesh a few time, the M7 looks as good as it can.  Long frame and short-frame versions are available, as also modelled are the versions with without sandboxes on the splasher.  Illustrated below are (from front to back)  a short-frame version, a long-frame and lastly a short frame without the sandboxes.

The picture below illustrates the different frame lengths, with 2 short frame versions sandwiching a long frame.



All version’s LSWR, SR, BR all as good as it gets with perfect fine lining.  The olive green in particular has real depth.

Running Qualities:


Smooth, quiet and reasonably reliable over most track, not suffering from derailing.  The wheels and track need to be kept clean though.

Relative Power:


I’d say around half the power of the prototype (and that’s being generous.)  Despite not having traction tires, it’s better than the T9 though and Hornby have done really well considering how awkward an 0-4-4 tank arrangement in 00 scale is especially for this slender this Victorian design is.  Take my example and buy 2 or more for a bit more omph!



Pretty good.  NEM pockets, DCC socket/fitted versions but no DCC sound version yet (not sure where a speaker could go – perhaps the bunker.).  Little space for a decoder limits decoder choice (click here for DCC fitting guide), unless you take weight out of the bunker – though this is improved in the more recent models.



High retail price for a non-limited production run model.  Second-hand prices however are very good, as the model has been on the market for some time, expect to pay £45-£55 for a mint version.  If buying secondhand, make sure you do not purchase the vastly inferior Triang version!

Overall Locoyardometer Score: 4.1

Only scores slightly higher than the T9, but is a better performer and more reliable.  Despite the score it is highly recommended, it’s a lovely model of a locomotive with a lot of charm.

Detailometer 5, Outlineometer 5, Finishometer 5, Motorometer 4.5, Powerometer 2, Specometer 4, Valueometer 3.5, Locoyardometer 4.1

One thought on “Hornby Ex-LSWR M7 Review

  1. Truth be told, I think the power is meant to be low, since these are mostly branch line engines for light loads over a small distance.
