Rated 4 out of 5 by LegoPanache Flex Track Best Practices
I took the challenge of effectively employing flex track in my layouts and derived a set of principles for improved play experience. Using flex track can offer a degree of granular control not previously available. I would recommend snatching up a few of these while they are still in production.
1.) Use flex tracks as spacers:
When using this technique, I lock one flex track element into the straight position using a 2x4 dark stone gray tile placed in the center of the flex track. This prevents the layout from changing shape as the train passes over.
curve radius 1: curve track only
curve radius 2: 1 curve track 1 spacer (repeat)
curve radius 3: 1 curve track 2 spacers (repeat)
curve radius 4: 1 curve track 3 spacers (repeat)
While other radii can be achieved, the various configurations above hug each other nicely and create aesthetic appeal.
2.) Use only one or two conjoined flex tracks when not locked into position. I only use flex track to make very fine angle adjustments in my layout. For example, to offer a minimal amount of leeway in my angle, I may place one flex track at each end of a long straight configuration in order to achieve a gentle and elegant slope, or to make a minor correction here and there.
3.) Due to the loss of traction when passing over flex track, I can leverage a series of flex track locked into a straight position to slow a train prior to entering a curve in order to prevent derailing. This is a helpful effect to prevent inexperienced locomotive engineers from launching the train at full speed around curves, or anywhere that deceleration is desired; for instance, near a train station.
4.) Add a spacer during elevation. Due to the change in angle when a track climbs in elevation, the situation may require an alteration of track length to accommodate the trigonometric effect. A single flex track used as a spacer is often helpful in this circumstance.
While somewhat awkward, I recommend trying to incorporate the flex track into your layouts and leveraging the unique characteristics of this piece. I own hundreds of them and employ them regularly with delight. Learn the subtle nuances of this piece and gain a new twist on LEGO track layouts.
Regarding straight tracks, these elements are so useful, that they should be offered in sets of straight track only (maybe x20). Additionally these should be sold individually in the pick a brick store.

The straight tracks are simply great, no complaints for them. The flex tracks make my track layout sloppy. The flex tracks could be much improved by having a locking mechanism. In that way they would be able to be locked into positions of straight, curve to the right or curve to the left. The track layout would be much more stable for the trains to travel over them. I stabilize my flex tracks now by using 2X4, 2X8, 2X12, or 2X16 plates. This works great for stabilizing the flex tracks as straight track. But my biggest problem is how to stabilize the flex track for curves!

I bought this set for a train I'm building, assuming that 16 curved pieces would be enough to make a complete circle or oval. In reality, the 16 curved pieces are only enough to make a single 90 degree turn. It would take four of these sets ($80!) just to make a full oval!

Rated 1 out of 5 by ChyCha Dont like those Flexible tracks
I never had a Lego RC train before I got the 7939 Cargo train as a gift a few years ago. Naturally I wanted to expand my track, but this was after they discontinued 7896 (straights & curves pack). I found myself looking at the Lego shelves and all i could see was this flex and straight pack, and no curves. The only option for curves was to buy another trainset or lots of 7895 (Switching tracks) which also includes 4 curves. I understand that Flex is supposed to be a multipurpose-track, where you can use it as a curve or straight as you see fit. The idea is great, but products that try to be two things, usually dont do very good in either, which is the case here. The flex track moves every time a train goes over it. The longer the stretch of flex tracks the more it moves. My Emerald Night struggles with it and the track sticks out from the rest.
I do, however, see a usage for the Flex, where you take 1-2 pieces together with straights to make a big curve. My 7939 Cargo train came with 16 flex, and that is basically all you will ever need. To include 16 Flex every time you want some straights, is to me a bad combo.
Please bring back the assortment from the good old 9V era where you could buy boxes of 8 pieces of curves or straights and the 4519 (crossing).
Please also bring back the 7996(double crossover).
I can not recommend this pack for its price because of the flex track. The straights are as always superb.

Rated 4 out of 5 by FredFerreira84 good extra tracks but expensive
it was useful just found it a bit expensive, and even by buying 4 boxes of this set I wasn't able to do a nice circular rail track for my creator expert horizon train.

Rated 2 out of 5 by Legoman7277 Bring back the old track sets!
I think we can all agree when making a lego city or a lego layout where we plan on having a lot of trains straight track is the essential and hard to come by. Most Lego train sets come with no or very few straight track so we all come to this set. Lego track is very overpriced and I think the flexible track is not very useful, unrealistic, and looks bad. Now yes flexible can come in handy if you have a tiny spot to fill whether is a curved spot or a straight spot. But sell it separately. Flexible track does have its own set, but why doesn't straight track? I think a set with 8 straight track for $9.99 would be a life saver for those who need bulk quantities of straight track and don't need or want the flexible track. Also what ever happened to the old track sets. The double crossover set was amazing and was very popular to consumers, yet Lego discontinued it. Now to get it is $150+. Also the simple cross over track we saw in every era of track from 4.5v to 9v yet they decided not to make one in RC track form. What ever happened to the old Lego track days. I think if you just need extra track this might be a good set for you. But if you just need straight track in bulk quantities of it I can not recommend this to you.

what can you say about the best toy in the world. this set is needed to expand your lego train track.

Rated 4 out of 5 by LostKey Good gap filler
This set is good for filling small gaps in the track, and adding strength to curves that are prone to coming undone. I made an X-crossing with four of these, and was very pleased at how it worked in a traditional figure-8 track. I also liked how they connect with the switches, so that you don't have to have a million inches of track connecting them.
