Before June 2008 came by, The one and only R40 Slants ran on NYC Subway D Train for not only Yankees Special but for certain construction when the D Trains ran in 2 sections

Between Norwood-205th Street And 2nd Avenue (Via the 8th Avenue Line Southbound)

Between West 4th Street And Coney Island

When did that construction, It was actually FUN and the D Train had VARIETY instead of the normal R68 Subway Cars. But then after June 2008, The R40 Subway Cars no longer ran on the D Train (Even the R40M and R42 didn’t run). I’ve ridden the R40 D Train from 125th Street to 2nd Avenue a few times. GREAT RIDE. You get look through the front window and see the tunnel. R40 D Train was really nostalgic/nostalgia. After riding it to 2nd Avenue it was really cool. Too bad I didn’t record a video of it though. Riding it via 8th Avenue was FAST. The R40 D Train was a really cool experience and felt like a time tunnel.  But anyways the R40 D Train is cool, only downside is that it only ran underground.

The R40 D Train is good BUT not better as an R68 D Train (In My Opinion). Wish I rode the R40 D Train more back then. But I’ll give the R40 D Train a 9.5 out of 10.
