  1. The Replica FO and BCK look to to be from the same stable and they were sold alongside Replica's version of the Mainline RB. Were they originally developed by Mainline or did Replica design them to match?
  2. Yes, that is correct. Most Dmus have horizontal engines, i.e. turned 90 degrees to the vertical. On the BUT engined cars (AEC, Leyland and Albion) the cylinder heads face outward with the crankcase towards the centreline, whereas Rolls Royce engined cars such as the 110 face the other way with the crankcase outwards and the cylinder heads towards the centre. Presumably this is due to which side the engine auxiliaries such as the injection system are mounted.
  3. I've just fitted one of these, thanks for the tip. It just slots straight in and running is much smoother with no jerk when pulling away. I meant to fit a K1 motor but didn't get around to ordering one before they all disappeared.
  4. The brass bracket that hold the motor in place, which is screwed to the chassis so presumably live as well, appears to be touching the right hand brush holder and thus it is not isolated from the chassis.
  5. Is the motor mounting bracket in contact with the right hand brush holder? It looks like it is in the photo.
  6. There are a lot of differences in the new Streamline points in addition to the flangeways. The spring is back underneath now, the blade pivots are different and the little contact tabs on the blades have gone (never were on the code 75 ISTR).
  7. They could date back to the 80s, early 90s was when I last bought any code 100. Just tried a Hornby 25 that I bought in the late 70s and have never knowingly adjusted the b to b and it runs through the new streamline points. Checked the b to b and its 14.1mm. Did Hornby increase their b to b in the late 70s? Will see if I have any 80s Hornby and check it.
  8. I've already swapped them with some Jacksons I had in stock (small dia, 10.5mm?). Comparing the new Peco code 100 points with the equivalent code 75, they appear identical apart from the depth of rail. Estimating with a piece of 40 thou plasticard, I would say 1.25mm flangeway is about right. The old ones look to be at least 1.5mm.
  9. They are 13.8mm B to B (or thereabouts). Plastic wheels on metal pin point axles. The flangeways on the new code 100 points look to be the same as those on the code 75 FB points used on the scenic part of the layout.
  10. Peco tightened up the flangeway on Streamline points sometime in the last 30 years. I have been building a new fiddleyard using small radius insulfrog code 100 points bought in the early 90s at the latest and ran out so had to buy some new ones (same type) to finish off. The flangeways are noticeably narrower on the new ones which struck home when I tried to run a Triang Hornby Murgatroyds tank through them and they jammed, whilst running happily through the old ones.
  11. What about the spreadsheet that the paper describes? https://www.nmra.org/sites/default/files/standards/sandrp/pdf/curved_track_center_and_obstacle_clearance_assistant_jul_2017.html It's under RP-7 in the recommended practices. https://www.nmra.org/index-nmra-standards-and-recommended-practices
  12. There were 3 classes on the Harwich trains pre-war, the 1938 'Hook Continental' set was first and second only with third catered for by a separate train. I believe that post war the seconds became thirds until they became seconds again in 1956.
  13. The problem I had when fitting Replica Commonwealths to Lima Mk1s was that using the correct size 14mm wheels the flanges touched the underside of the floor if the ride height was anything like correct. I ended up having to cut slots in the floor to allow space for the wheels.
  14. If it's the Hornby self contained motor bogie, similar to the one that's used in a lot of their multiple units, I've found that they don't respond well to the Bachmann chips. You may find that turning off the back emf helps, on my 153 it at least made it controllable but in the end I swapped it for a Lenz Standard + which works great. The Bachmann chips seem to work best with their diesels and units with big motors and flywheels.
  15. How does the original Bachmann 158 chassis match up. I know some people used to put it under a Mk3 coach to re power HSTs in the days before the super detail one came out and I've also seen one in a 442 EMU.
