Locoyard Review

Bachmann ex-LMS Ivatt 4MT 2-6-0 43160 (cab)



Detailing parts are plastic, but look good.  It has no cab details picked out but as it has an enclosed cab, this doesn’t make much of a difference for everyday running.  It has a fixed open cab roof, lamp irons, handrails and piping.



A complex prototype expertly captured by Bachmann.  There is daylight where it should be and the valve gear looks spectacular.  Excellent stuff!

There is a visible line created by the moulding along the top of the boiler and chimney, but it’s not too prominent.  Finish is very good other than this, as usual from Bachmann.

Running Qualities:


The motor growls a little so it is not as quiet as some models, but it works well and is easy to control.  It lack’s pick-ups on it’s tender wheels, but fortunately this has not given it it problems with stalling.  The chassis is not particularly sensitive on rough track and runs well overall.

Relative Power:


On tight 2nd radius curves 3-4 bogey carriages is a maximum before some slipping occurs, though it will pull 6 before it stops dead in it’s tracks.  It is underpowered and not as capable as it should be.  Make sure the mechanism and valve gear is lubricated properly, as this makes a big difference.

Specification is reasonable with NEM pockets, sprung buffers, DCC socket/fitted versions but no DCC sound version yet.  It has a body mounted 8 pin DCC decoder socket with very little room for a decoder, making fitting a a challenge.  Lamp irons, handrails and reasonable detailing with a good finish, complete a reasonable but not spectacular specification.

Perhaps due to it not being the best looking type,  dealers give good discounts on this model.  Model’s regularly appear for little money on the second-hand market.  Look at paying £45-£55 for a mint secondhand model or £60-£70 new.

Overall Locoyardometer Score: 4

This model is good, but not quite as spectacular as some other reviews may have you believe.  It’s not as strong as it should be and there are quieter mechanisms out there too.  Credit where it is due – it looks good and there is lot’s of daylight where it should be.  Creating this model must have been quite a challenge!  It’s not a bad model, just be sure to part with as little cash as you can when buying it.
