  1. I started with BR LM in May 1976. Student Technican Engineer was my job title. I spent 5 happy years training with many different departments within the S&T.

     

    My job, post training, was in the signalling drawing office in Birmingham, but after only 18 months I made the worst decision of my life and left for a job at Froude Engineering in Worcester. The money was far better, but it was the end of a career. One by one the heavy engineering jobs vanished from Britain, and I have never had any sense of belonging with any job I’ve held since.

  2. Until some curb is put on the level of population increase both from immigration and procreation, this problem will never be solved. Since tackling either issue is political suicide, continuing congestion, road building, house building and even railway building are forecast for centuries to come.

  3. You have shown the protrusion of inside cylinders and outside cylinders as well, so the front truck is a 4cyl! This could be an inside 2cyl truck, which would help on curves, and be the high pressure, small volume truck. The front buffer beam needs to be attached to the truck, not the boiler too.

  4. BR once had a proposal to build containers which could be lifted on and off flat wagons by a skip lorry (dumpster truck). It could have saved the wagon load / less-than-wagon-load traffic from oblivion. I rather like the idea of a pickup goods train pulling into a wayside station with half a dozen lorries ready reversed up to the platform edge.

  5. I suspect that even at 80:1 most model locomotive motors are used right at the bottom of their performance curves. Flywheels help to impove that situation, but ideally the higher the gearing the better.

     

    The formula for inertia (I) includes radius squared, and the formula for kinetic energy of a flywheel includes omega (radial velocity)squared so you are right to cram as big a radius flywheel as possible to maximise its effect. Long thin flywheels are bad engineering.

  6. Super 4 track is very close to scale sleeper spacing for 4mm : 1ft. The rail is of course deeper than code 100.

     

    I suspect that system 6 was an attempt to challenge Peco on one hand, and to achieve economies of scale by making one track for UK and European markets on the other.
