Some neat woodwork on the cassettes mine were very basic. I presume using dinghams you do not need the same access to the couplings as needed for three links.
No Don, that's right. Uncoupling is easy from above, recoupling is automatic. In fact no "shunting" (rearranging) of wagons will take place while they are on the cassettes, except to move the brake vans from one end to the other. For this I plan to use a special transfer cassette which won't have the brass strips and will only be used to move the brake vans. Each train of wagons (7 + brake) will take up two cassettes. Variety in returning trains can be the result of different combinations of pairs. Of course wagons will get shunted in Dock Green yard into different combinations.
With regard to the foamboard I find the no nails type of adhesive similar to PVA in grab time. I have been using unibond megagrip for building work it seems pretty good for fixing skirtings and the like. BTW I find that even with low relief buildings some internal floors even if just narrow strips does help to make the structure more rigid. I tend to cut out the parts then assemble the structure and leave to set. I also find bits of masking tape useful to hold parts together whilst setting and it can be used on the outside round a join but be easy to remove later.
I agree with you about the internal floors, the warehouse is pretty big so has two of these and also partition walls in line with the "pillars" in the facade. there is also a back so that it's not possible to see right through. Once brick sheets are glued on I find the structure is quite substantial and much less prone to dents - although you do have to take care not to bruise corners. I haven't bothered with masking tape on joints - I rely instead on dressmakers pins. However these do slide in and out very easily so to keep a joint together they must be numerous and put in dovetail fashion.
A rear view of the warehouse showing how the ground and first floors are very shallow to allow room for the cassette area. The top floor goes right to the back, mainly to strengthen the side walls. I glued a length of pine at the base of the front wall and another piece is glued vertically into the unsupported corner on the left. The "leg" locates in a square socket of stripwood, the front bar is drilled and drops onto two dowels protruding from the baseboard surface.
The length of Peco track you can see is the headshunt. I couldn't persuade the bloke who laid the track that it was pointless to paint this section!
I will post pictures of the front of the warehouse soon.
