Hi David.
The Peco catalogue doesn't tell us enough to be able to add it.
Gauge 9mm.
SL-400 (Flexi track) L=36" (914mm)
SL-E491 (R/H Turnout) L= 4 5/16" (125mm), R=12" (304mm), A=19.5 deg.
SL-E492 (L/H Turnout) As above.
SL-E497 (Y Turnout) L= 4 5/16"* (109mm), R=18" (457mm), A=22.5 deg.
SL-427 (Wagon Turntable) No dimensions given
* Clearly incorrect. The Y turnout is 3 sleepers shorter than the normal turnout.
For interest: HOm (14mm gauge)
SL-1400 (Flexi track) L=36" (914mm)
SL-E1495 (R/H Turnout) L=6 5/16" (160mm),R=20" (508mm), A=10deg.
SL-E1496 (L/H Turnout) Ditto.
SL-E1486 (R/H Curved) L=9 3/8" (237mm, R1=18" (457mm), R2=24" (609mm)
SL-E1487 (L/H Curved) Ditto.
SL-E1493 (Diamond X) L=4 5/8" (117mm), A=20deg.
LK-1455 (Turntable) No dimensions given.
Hope all that helps.
Best wishes,
Chris.
PS. How about having a thread specifically to notify us of updates to the program?
