the Fifer way , it should work on snap on HO top's , also the Bachmann way

no problem with my Hornby Elite with Select walk around (DCC) on Bachmann (the Hornby system has bad reports - I find its not too good/happy with MRC decoders)

hi , light mountain in Southern livery ...

160 mm cow catcher to rear of tender
175 mm coupler to coupler (dummy front - Bachmann EZ buckeye tender)

hope this helps - 

also worth a mention big loco's like the Bachmann Centennial DD40AX
wont revolve full circle on the Atlas TT , as the coupler/pilot catches the motor/gearbox housing on the turntable .
 

hi - I am in UK , and have all the new 00/H0 Bachmann Thomas , Toby is the noisy engine  , maybe because of the box like body acting as a sound box , it is a nice slow (on analog DC) runner apart from the 'whine'

I have run in but not lubed/oiled yet.

also of note , when compared to the Hornby Toby it is a better smaller size , also Bill & Ben in Hornby are wider than Hornby's Toby .

cheep lights (LED) from the £ pound/$ dollar shop - a string of xmas tree lights battery powered , about 3 - 4.5 volt .

good old Bachmann - remiss of the past - white box and before era 

when they bought a lot of smaller (life like and others) model railroad manufactures out  , and the couplers

was at all different heights , it now looks like they are shoving it into train sets 

Bachmann have pulled their socks up over the past couple of years , although their N scale stuff still suffers split gears

Bachmann please catalogue some HO/00 scale people from the Thomas series

Bachmann please keep the coupling the same --- Gordon's coach's - Annie/Clarabelle and others  use old Mainline/Bachmann (UK) coupler . but I notice Toad brake van and other stock use NMRA smaller coupler (UK) but the hook on the older coupler do not enter the loop on the smaller version - thus when cornering the unattached hook throw's/derails the attached wagon/car ?

this is a kids toy and kids love speed and NO derailments

thank you .

a new Thomas fan (UK)  , recent up grade to the 00/H0 layout - Thomas Percy James and Gordon - but Gordon derails his tender mostly on track joints (Peco track) and extra large radius curves - after 3 mods the only cure was deeper flange wheels (Trix 1970's vintage) so Bachmann please listen larger flange on Thomas range - this is a kids toy and they love going at full speed

after that they are better models than the Hornby range .   

Bachmann get new models out quickly and stop causing confusion and delay 

not into Thomas but looking thru' Hornby (UK) new loco for 2021 - as they used to manufacture Thomas (you know the rest  )

I notice they have used both the 4 and 6 wheel Thomas loco as industrial loco's and Percy also been used as a industrial loco

that's manufacturers - get rid of existing stock ,

happy modeling guy's

Bachmann maybe slow to respond with the virus thing'y     on the prowl , I saw some where they are not accepting order in present times  ,  I know the clip locations for the 6 pin N scale plug in - but not for the 8 pin (HO ?)

do you have to wire each exit track separate with its own switch ?

my turntable (Atlas) is DCC and half of the tracks are wired +/- and the other half  -/+ the feed track is +/- , the motion of the table reverses polarity (hope this makes sense ?)

I model both N and HO (not Thomas) my local shop (in UK) has a Thomas set (HO) in stock and its very tempting so when they open on Tuesday ......

happy modeling guy's for 2021

hi , you are not been ignored ( ) please be patent as its holiday time , as I only run single line I can not answer your question - may be you could try a post in the general discussion then the HO guys will help out , as it is only power to the track/trains

have a good year ahead
