I have been driving the N and Q routes from Astoria, and I found some things which I think are bugs:
On all of the stations on the Astoria Line, the exit stairs should be facing
away from each other, not towards each other as they are in the route.
←] [→, not [→ ←].
The Astoria Boulevard station has a shelter on the Manhattan-bound platform around the stair facing the south end of the platform.
It appears in this photo:
1172There appears to be two signals too close together between Ditmars and Astoria Boulevard.
Two signals appear too close together on the middle track at Broadway.
The lower level platform at Queensboro Plaza (yes, the B is lower case, and the -ugh is omitted) is too far away from the curve. It should be closer to the GT15 sign. Remember that the east end of the lower level platform is actually below the diamond on the upper level.
The signal beyond Queensboro Plaza should be a home signal ( track.section 0;0;2, track.sigF [appropriate home signal object with bottom green];
The curves beyond QBP are not sharp enough.
The behavior of the timers on the ramp down to the portal doesn't feel right. They should behave, given the proper route selection, so that the train clears the aforementioned curves outside Queensboro, then allow the train to accelerate to about 35 or 40 by the time the train reaches the portal, then get close to 60 by the bottom of the tunnel.
The curves at both ends of 5th Avenue are not sharp enough.
Anyway, just my 5 cents.
