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. the BEARING RAILSThe bearing rail (sleepers) was installed as the Foundation on which the rails are firmly laid and rods. Serve to (1) put and holds the rod rail, (2) keep kelebaran track (track gauge, is a measure of the width of the track Rails. Indonesia has a track gauge 1067 mm) so that it is always constant, in other words in order to stem the Rails do not stretch or narrows, (3) centering gauge Rod so as not to bend down when passed a series of KA, as well as (4) transfer the axle loads received from landing plate Rails and rods for spreading a layer of stone ballast underneath.Therefore, the bearing must be strong enough to hold the rod in order not to rail were strong, as well as to withstand the load circuit of KA. The bearings are mounted transversely from the position of the Rails at distances of up to 60 cm. antarbantalan there are three types of bearings, i.e.:(1) bearing wood (Timber Sleepers), made of wood or wooden sticks mix, which is coated with creosote (wood coating oil) to make it more durable and resistent(2) bearing Plate iron (Steel Sleepers), is the second generation of cushioning, durability of wood. Iron bearing not mounted on tracks or on eletrifikasi ter-tracks that use electric persinyalan(3) bearing reinforced concrete (Concrete Sleepers), is today's modern bearings, and most widely used because it is more powerful, durable, cheap, and able to withstand a load of greater than two other pads.
