2. BANTALAN REL
Bantalan rel (sleepers) dipasang sebagai landasan dimana batang rel diletakkan dan ditambatkan. Berfungsi untuk (1) meletakkan dan menambat batang rel, (2) menjaga kelebaran trek (track gauge, adalah ukuran lebar trek rel. Indonesia memiliki track gauge 1067 mm) agar selalu konstan, dengan kata lain agar batang rel tidak meregang atau menyempit, (3) menumpu batang rel agar tidak melengkung ke bawah saat dilewati rangkaian KA, sekaligus (4) mentransfer axle load yang diterima dari batang rel dan plat landas untuk disebarkan ke lapisan batu ballast di bawahnya.
Oleh karena itu bantalan harus cukup kuat untuk menahan batang rel agar tidak bergesar, sekaligus kuat untuk menahan beban rangkaian KA. Bantalan dipasang melintang dari posisi rel pada jarak antarbantalan maksimal 60 cm. Ada tiga jenis bantalan, yakni :
(1) Bantalan Kayu (Timber Sleepers), terbuat dari batang kayu asli maupun kayu campuran, yang dilapisi dengan creosote (minyak pelapis kayu) agar lebih awet dan tahan jamur
(2) Bantalan Plat Besi (Steel Sleepers), merupakan bantalan generasi kedua, lebih awet dari kayu. Bantalan besi tidak dipasang pada trek yang ter-eletrifikasi maupun pada trek yang menggunakan persinyalan elektrik
(3) Bantalan Beton Bertulang (Concrete Sleepers), merupakan bantalan modern saat ini, dan paling banyak digunakan karena lebih kuat, awet, murah, dan mampu menahan beban lebih besar daripada dua bantalan lainnya.

2. BEARING REL
sleepers (sleepers) which is installed as a foundation is laid and tethered rod rail. Serves to (1) put the tie rods and rails, (2) keep the width of the track (track gauge, is a measure of the width of the rail tracks. Indonesia has a track gauge 1067 mm) so that always a constant, in other words that the rods do not stretch or narrow rails, ( 3) rail rods rested so as not to bend down when being passed series of trains, as well as (4) transferring axle load received from the stem off the rails and plates to be distributed to the ballast rock layers underneath.
therefore the bearing must be strong enough to hold the rod rail so as not to shift, as well as strong to support the weight of the KA series. Bearing mounted transversely of the rail position at a distance of 60 cm maximum antarbantalan. There are three types of bearings, namely:
(1) Bearing Wood (Timber Sleepers), made ​​of real wood or wooden rod mixtures, which are coated with creosote (oil wood coatings) to be more durable and resistant fungi
(2) Bearing Plate Iron (Steel Sleepers ), is the second generation of the bearing, more durable than wood. No iron bearing mounted on tracks that were well on track eletrifikasi using electrical signaling
(3) Bearing Reinforced Concrete (Concrete Sleepers), is a modern pads today, and the most widely used because it is strong, durable, inexpensive, and able to withstand the load larger than the other two pads.
